Hey but this program eats 18mb of memory in 10 or so iterations!!!!
It is not just question of leaving a bucket (also because I free each block
before asking for a new one).
Since I'm on a sun now I can't verify but I'll check to see if the trouble
is still up with fixed memory sizes. I think so because I have the same
problem with a real application (my picture viewer) that (of course)
allocate and free big chuncks of memory...
