It's not the compilers, but rather the runtime that manage the memory
pools, and yes, Cygwin's memory manager does do pool optimization just
like every other `malloc' package out there.

Cygwin's malloc is based on, as far as I can tell, Doug Lea's public
domain implementation. See his homepage http://g.oswego.edu/index.html
for the design document (go down to the "Software" section).
