It should be sufficient to link in jemalloc.  Note however that as far as I know, glibc still has what amounts to a huge stl memory leak that can be worked around by defining GLIBCXX_FORCE_NEW=1 in the environment when running your application.  tcmalloc does this automatically, but jemalloc does not.
