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.
