It appears Igor is right. Even if I just do:
Y:=String new: 550000000.
nothing I do other than rebooting the image seems to recover that
memory for other processes. But rebooting the image is not an option
for a 24x7 server.
I hope this can be fixed because it really neuters Squeak's ability to
outshine other systems by its flexibility.
