I know, it's terrible, but it's all I've come up with so far.  Maybe we
need to rethink how the size-limiting modules work so that they can use
something like the total amount of free physical RAM instead.  I think
that's sort of what you were thinking of too.

Me too, but I'm not holding my breath.  We can find out how much total
memory is free though, at least on Linux.
