If this is really due to heap fragmentation, then there
must be a bug in the underlying malloc and free. I can't
imagine the memory keeps growing when all the dynamics are
due to getting and freeing memory for labels between
10 to 36 characters in length. Initially, we will create
useless fragments. But, due to the pigeon-hole principle
(http://en.wikipedia.org/wiki/Pigeonhole_principle)
those fragments cannot remain entirely un-recyclable
even if "free" is very unthinkably simplistic and does not
merge adjacent fragments.
