Hi Don,
I was wondering if perhaps this might be a slightly better instance
for Binary [a], that might solve a) the problem of having to traverse
the entire list first, and b) the list length limitation of using
length and Ints. My version is hopefully a little more lazy (taking
maxBound
Hello,
Using encode/decode from Binary seems to permamently increase my
memory consumption by 60x fold. I am wonder if I am doing something
wrong, or if this is an issue with Binary.
If I run the following program, it uses sensible amounts of memory
(1MB) (note that the bin and list' thunks
I just need a small test case to reproduce the problem.
Thanks!

Hello,
Is there a work-around? This is killer for Happstack. Most Happstack
applications use IxSet, which in turn uses lists to serialize the data
to/from disk.
Also, why doesn't the stuff get freed eventually?

On Fri,
Why don't you use your own instance to serialize IxSet lazily (or
however you would like?)
There's no reason to be constrained to use the [a] instance.

It is my understanding that the GHC runtime never lets go of
memory once it has requested it. (Confirmation either way
would be informative.)

It doesn't return memory to the OS.

Well, the Set instance might actually be a better choice. But the Set

I don't think so. In happstack, the idea is to have all your state in
RAM. But, since your

I think actually, that my test program was a bit

Ok,
I fixed my test program, and now things seem more reasonable. The
original version was allowing the GC to collect the list in the first
case, but not the second. However, I don't want the list to be
collected. The new version seems to fix that issue. Now the control
uses 40MB and when I
