I haven't yet come up with a solution to the GC hanging problem I
mentioned the other day.
But here's something that looks funny. I changed the default minor
heap size, the major
heap increment, the allocation policy. I also threw in a
`Gc.major_slice 0' in the code.

It did work as expected.

maybe you wrote "sudo echo 0 > file" or something similar which perfoms the
echo as root but the redirection as normal user ?___

Hi,
I recently had similar output from the GC (huge count of words) which
I noticed after my program started to exit with an out-of-memory
error. It doesn't seem to be happening anymore but I'm not sure I
"fixed" it. There are three things I thought of to get rid of it.
(btw, I'm on 64bit linux)

David and Basile, you are absolutely right about the redirection
issue. It also pretty obvious actually. I guess I need to pay more
attention.
Back to the original problem, I thought I had somehow gotten rid of it
but it still happens on someone else's computer. Calling 'Gc.compact'
regularly seem
