I think using _Thread_Disable_dispatch() as the giant lock is a big problem. 
How can you introduce finer grained locking without a massive re-structure of
critical section in this case?  It is very desirable to make the thread
dispatch disable level local to a core and use it for a core-local thread
dispatch disable.  It would be very nice to have a document which cover the SMP
design decisions resulting to the current patch PRs.
