Shouldn't be much of a problem... But 'eh, does the
Mersenne program regularly do memory I/O?
It could be that it loads large chunks of memory and
frees small portions from the middle of it. The Linux
MM system could have a problem with that...
Of course we should be able to handle such stuff, but
with the current buddy allocator things might just get
a little bit tricky :(
The reason I picked this process, is that it's RSS is
only one 18th of it's total size, which is somewhat
weird for a 'normal' Unix process.
