   No, I think that's why it's so blasted slow.

   Yeeesh.  If not memory leaks, perhaps memory fragmentation?  If one 
isn't using a low-fragmentation malloc() implementation, malloc() arena 
fragmentation can really hose you...if the malloc() code keeps needing 
to call sbrk() to increase the arena size rather than coalescing 
smaller blocks into larger ones upon calls to free().

   The old system-supplied malloc() that came with NetBSD in the 1.3 
days is particularly bad about this, I can say from personal experience 
and a remaining anal burning sensation.  I solved that problem very 
effectively by replacing it with a package called "dlmalloc" which you 
may have heard of.
