History
Tor Egge df140f7277 When multiple threads call atexit at the same time, some operations must 
be serialized.  A mutex is used to protect the critical regions.

sbrk() and brk() are not thread safe.  Replace use of sbrk() with
a call to malloc to avoid race when one thread calls atexit
while another thread calls malloc.
