Hi David,

I think you might want to talk with Jonathan Morton about
your situation. Jonathan is working on a non-overcommit
patch which will make sure no more memory is malloc()ed
than what is available.

Chances are this patch will stay separate for the kernel
for some more time and get integrated later when it is
well-tested and there is a certain userbase who really
want/need the patch (I suspect both of these will happen
rather soon, though;)).

regards,

Rik
