Only if, as Craig said and you disputed, you have overcommit enabled
or lots of swap.

There is a problem though, if you have overcommit disabled you kind of
need lots of swap to avoid running out of virtual memory long before
you're actually short on physical memory. And it's true that Linux has
had trouble dealing with low memory situations in the past few years,
at least in my experience. But that's not true on all OSes and we can
hope it won't be true for Linux forever too.
