    kernel - Change lwp_fork() to not hold the mplock in the new thread
    
    * Change lwp_fork() to produce a mpsafe thread at startup instead of
      one with the mplock held.
    
    * Change all fork_trampoline() functions and all kernel callbacks
      via cpu_set_fork_handler() to expect a thread without the
      mplock held.
    
    * Adjust the thread procedures for aio etc (those not yet mpsafe)
      to acquire the mplock.
