Mem leak : malloc/free + pthreads = leakage?

I would try playing with MALLOC_OPTIONS. I seriously doubt that there
is an actual leak in jemalloc, but from my own experiences with it I
suspect that there are certain multithreaded malloc/free sequences
that interact badly with with the per-thread caching that jemalloc
performs. The first thing I would try is setting MALLOC_OPTIONS=7h to
disable the caching.
