just about any OS will fall over if/when it runs completely out of memory.

there *is* an option somewhere in recent kernels (don't remember if it's
compile-time or runtime), that will allow you to turn off memory
overcommitment; i.e. the kernel will only allow programs to allocate a total
amount of memory <= RAM + swap.

this still doesn't catch all cases; but most of them.

be interesting to see what happens in the case of pan grabbing all the
memory it can, but not being allowed to overcommit. I'm thinking it would
just fall over, but hopefully not take anything else down with it.
of course, this is still bad behavior, and should be dealt with in any case.
