USE_LOCKS won't help multi threading performance.  It just adds a global
lock we already have.  We could probably get rid of the locking calls
in mm/malloc_wrapper.cc. Nice, but no help performancewise.

We could try to enable MSPACES (but not ONLY_MSPACES) and redirect
all malloc calls from user-space to per-thread mspace_malloc calls.
That may be worth a try.
