And in researching the problem I see that this is a well trodden path.
I found a particularly useful thread from 2006 entitled "better malloc
strageties" in the OpenLDAP archives.  As I result I packaged up
libhoard, installed it, and re-ran the valgrind test.  The short test
showed no memory leaks.  I will perform more extensive tests, but this
appears to have fixed the problem.  Thanks for your work, then and
now.
