Comment (by RJVB):

 leveldb has been depending on gperftools since the beginning, so you could
 have known :)

 And the tcmalloc dependency is purely private to leveldb, there are no ABI
 differences, in fact, even the leveldb code doesn't contain anything
 that's tcmalloc-specific. My patch only disables the linking-in of
 tcmalloc; the current variant is no different than the optimisation (or
 debug!) variants other ports propose.

 You can get back the "stock" leveldb behaviour by doing the equivalent of
 `LD_PRELOAD=libtcmalloc`.

 Maybe read up a bit on the subject to make an informed decision? It'd be a
 pity to remove one of leveldb's sales arguments (its speed) just because
 it might cause side-effects. On my side I plan to sort this out further.
 Again, the issue might be caused by an issue in code I'm working on and/or
 a system bug in OS X 10.9 .
