Ah, yes, that's probably it. If I recall, the problem showed up for people
running the newer Linux 2.6 kernels (maybe only on 64 bit machines? I'm
not sure).  If I remember right, I think that it was possible to work around
the problem by forcing the VM to use a fixed memory allocation, something
like "squeak -memory 40m myimage". I don't happen to have a Linux 2.6
system or a 64 bit machine to confirm this, but it's worth trying the
" -memory" option to see if it helps.

Damien, essayez ceci:

  $ squeak -memory 40m squeak.image
