.B MEMBARRIER_CMD_PRIVATE_EXPEDITED
Execute a memory barrier on each running thread belonging to the same
process as the current thread. Upon return from system call, the caller
process as the current thread.
Upon return from system call, the caller
thread is ensured that all its running threads siblings have passed
through a state where all memory accesses to user-space addresses match
program order between entry to and return from the system call
(non-running threads are de facto in such a state). This only covers
threads from the same process as the caller thread. The "expedited"
commands complete faster than the non-expedited ones, they never block,
but have the downside of causing extra overhead. A process needs to
register its intent to use the private expedited command prior to using
it.
