OK - 'flaky' was a bad choice of words here. Point taken.

And yes, the replacement for the hasMemory function was actually just
an afterthought. What I really was after is what the OS thinks is the amount
of free non-virtual ram, for use in error reporting.

Since all modern operating systems will happily dish out virtual memory
and swap things around, I agree that seeing if you can allocate a block of
memory of a given size is somewhat less useful. What might be more useful,
though, is determining whether swap space is being used, which could have
significant impact on program responsiveness.
