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.
