  Log:
  Make tsleep/wakeup() MP SAFE for kernel threads and get us closer to
  making it MP SAFE for user processes.  Currently the code is operating
  under the rule that access to a thread structure requires cpu locality of
  reference, and access to a proc structure requires the Big Giant Lock.  The
  two are not mutually exclusive so, for example, tsleep/wakeup on a proc
  needs both cpu locality of reference *AND* the BGL.  This was true with the
  old tsleep/wakeup and has now been documented.

Kudos!  This is great work.  It also makes lwp work considerably easier 
in this area.  Thanks a lot!

cheers
