How much memory does the VM have (i.e., how much "physical" memory does
it report to the OS)?
Could it be that processing "jit.c" uses so much memory that the xform
process within the OS within the VM spends all its times paging, so it
seems stuck? I had that problem once.

In v5.0.99.7, when the plain Racket REPL is blocked waiting for input,
it yields to GUI events. That's different from previous versions, which
would leave the GUI frozen while waiting for REPL input.

Don't modify "configure" directly. Its source is "racket/configure.in".
But the problem for the releaseis that "src/plot" should be included,

Eli and I got horizontal wheel events working, at least on his machine.
It won't work in XP, because horizontal wheel events are only available
for Vista and up. Meanwhile, we also fixed the crash that Robby found

As of the latest in the git repo, when libffi is installed (including
header files), then `configure' detects it and uses it, instead of
building the copy of libffi that is included with the Racket sources.
Hopefully this will just work, but watch out for new `configure'
problems.

I tried a build with `--enable-shared' and the generated `mzscheme'

causes the problem.

you get an error like this?

the code a little harder, and using `in-range' or `in-list' can good

The problem is that `make install' cannot handle a path with a space in

It looke like you have `-L/opt/local/lib' in your LDFLAGS
configuration. Do you also have `-I/opt/local/include' in CPPFLAGS?

I would like to look closely at this. Can you send me a patch?

Here's a performance experiment (code enclosed).
Functions:
assq2 = plain Racket implementation of `assq'
assq-via-assf = `assq' via `assf' in same module
assq-via-library-assf = `assq' via imported `assf'
assoc2 = plain Racket implementation of `assoc'
assoc2/opt = like `assoc2', but
I've pushed the change that makes `assoc', `assv', and `assq'
implemented in Racket, including the new optional argument for `assoc'.

Well, here are some new numbers (32-bit):

The `assoc' example helped focus my attention on a long-unsolved issue
with JIT-generated code, where non-tail calls from JIT-generated code
to other JIT-generated code seemed more expensive than they should be.
This effect showed up in `assq' and `assoc' through a high relative
cost for calling `a

I forgot to reply to that point before. Unfortunately, I don't think

I don't think the current cycle-checking cost is significant. Also, if
a program uses `assoc' on a list that's long enough for locality of the
turtle to matter, then it probably has bigger problems. But don't let
me stop you from experimenting!

It looks like 20% of the time can be saved by JIT-inlining the
`procedure-arity-includes?' check that `map' performs. (And I've been
meaning to make that JIT change anyway, since it's an obstacle to us
That patch looks fine.
Do you have any process limits set? (My impression is memory is often
limited by default on FreeBSD systems.)

Does that avoid the bus error that you saw before?

I think I'm asking the wrong question. I should instead ask:
What does the man page for fpsetmask() say should be #included?
(The switch to #include was based on a FreeBSD man page.)

I've pushed fixes for kFreeBSD, so let me know if you encounter further
problems.
