Are there platforms where this is likely to be a problem? Presumably to 
avoid this sort of situation, Linux threads imposes a limit on stack 
size (32MB, IIRC), which would usually be hit long before virtual memory 
is exhausted. In the case where virtual memory really does run out the 
kernel will just start killing apps.
