David Goldblatt a011c4c22d cache_bin: Separate out local and remote accesses. 
This fixes an incorrect debug-mode assert:
- T1 starts an arena stats update and reads stack_head from another thread's
  cache bin, when that cache bin has 1 item in it.
- T2 allocates from that cache bin.  The cache_bin's stack_head now points to a
  NULL pointer, since the cache bin is empty.
- T1 Re-reads the cache_bin's stack_head to perform an assertion check (since it
  previously saw that the bin was empty, whatever stack_head points to should be
  non-NULL).

README 

jemalloc is a general purpose malloc(3) implementation that emphasizes
fragmentation avoidance and scalable concurrency support.  jemalloc first came
into use as the FreeBSD libc allocator in 2005, and since then it has found its
way into numerous applications that rely on its predictable behavior.  In 2010
jemalloc development efforts broadened to include developer support features
such as heap profiling and extensive monitoring/tuning hooks.  Modern jemalloc
releases continue to be integrated back into FreeBSD, and therefore versatility
remains critical.  Ongoing development efforts trend toward making jemalloc
among the best allocators for a broad range of demanding applications, and
eliminating/mitigating weaknesses that have practical repercussions for real
world applications.

The COPYING file contains copyright and licensing information.

The INSTALL file contains information on how to configure, build, and install
jemalloc.

The ChangeLog file contains a brief summary of changes for each release.
