Question - why does calling memp frequently crash the system?  Is the
buffer pool being exhausted and the code is not properly handling the
out-of-buffer condition?  Or is there bug in the memp code itself that
does not show up until the memp code is put under stress as in the your
test above?

I agree completely with this change - but more for performance aspects
of the change.
