I'm probably being dense here and not seeing the wood for the trees,
and I've included lots of tedious junk below, but here goes.
I have a program which runs too slowly. I knew when I wrote it that I
was taking a `naive' approach to the program - I've tried to write
what I meant rather than
-davenant:~/junk cat t.hs
main = error "bang!"
-davenant:~/junk ghc t.hs
-davenant:~/junk ./a.out
Fail: bang!
-davenant:~/junk ghc -prof -auto -auto-all t.hs
-davenant:~/junk ./a.out
Segmentation fault (core dumped)
-davenant:~/junk ghc --version
The Glorious Glasgow Haskell Compilation
Simon Marlow writes ("RE: ghc with shared libraries ?"):
Still can't be done, I'm afraid. At least for Haskell libraries; you could
compile parts of the RTS and libHS_cbits shared, but we haven't done that.

Simon Marlow writes ("RE: Change to Posix.lhs"):
Should we use a Maybe rather than an exception here? Probably, but then
System.getVar doesn't return a Maybe, and the Posix library as a whole has a
tendency towards exceptions rather than Maybe returns. So I'm swithering(*)
on this one.

Earlier I wrote lots of stuff about trying to build GHC from
1999-12-25 using the Debianisation patch from 19990916-3. I said I'd
try the Debianisation patch from 19991206-1 with an appropriate cvs
update, and I've now done that and the compiler seems basically to
work. Thanks, Michael, for

OK, here we go. The program is at

I just want to say that Haskell is a fat old slow
dinosaur compared with Clean. Download Clean at
www.cs.kun.nl/~clean and get rid of your Haskell
installation.

No doubt you're quite tired of seeing my mails by now, but here, have
another one :-).
I now have a couple of problems which look like they can be summarised

I'm writing a program which does

but not

GHC complains that the type constructor Socket isn't in scope.
Indeed, in Socket.lhs from GHC 4.04.19990916 I see that Socket isn't
exported, even though a function listenOn :: PortID - IO Socket is.
When I say

Before Christmas I reported a (known, I discovered) bug which would
result in the message `fatal error: No threads to run! Deadlock?'.
Simon Marlow replied then:
This is due to a locking problem with our I/O library. Basically, if the
program calls trace while writing to stdout (eg. using
