  Modified files:
    lib/libc/stdlib      malloc.c 
    lib/libc/include     libc_private.h 
  Log:
  Externalize malloc's spinlock so that a thread library can take
  it around an application's fork() call.  Our new thread libraries
  (libthr, libpthread) can now have threads running while another
  thread calls fork().  In this case, it is possible for malloc
  to be left in an inconsistent state in the child.  Our thread
  libraries, libpthread in particular, need to use malloc internally
  after a fork (in the child).
