It depends on exactly what happens, but yes, this sort of resource
starvation can affect linux also. In general, I find the problem to be
worse under XP because:
1) XP seems more susceptible to it - I suspect it's because of the way
it aggressively swaps non-focussed applications out
2) You don't have tools like ulimit to prevent it
3) You can't switch to a console or hard kill X, and in most cases you
can't log in from another machine to fix the problem.

I wasn't trying to contribute to the XP vs Linux punchup though, just
point out that this is consistent with known behavior in XP under
certain kinds of load, with the intention of helping the OP prevent
that kind of load.
