Me too.

Me too. :-)

But I think that it definitely is heavily OS dependent.
It should work in most *nix environments the first time
you call the function. But on second call I'd expect
all bets to be off. And in most real-time OS's memory
goes right back to the OS pool - but even there it
would probably be available I guess, at least the first
time.

Maybe the theory is that if you get a memory error the
only sensible thing is just to log it and exit. In which
case you only ever call this once.

Steven, Did you try any experiments? I'm struggling
to come up with a reliable test scenario.
