Check the PG list archives --- there's been previous discussion of
similar issues.  I think we concluded that when Perl is built to use
its own private memory allocator, the results of that competing with
malloc are not very pretty :-(.  You end up with a fragmented memory
map and no chance to give anything back to the OS.
