    sys/sys              msgport.h thread.h 
  Log:
  Add a MSGF_NORESCHED feature for lwkt thread-based message ports.  The
  idea is to use it to allow certain async messages to be queued to higher
  priority system threads and schedule those threads without forcing an
  immediate reschedule.
  
  The feature will be used by the new socket code to prevent cavitation
  between a user process and system protocol thread when the user process
  is write()ing a lot of data over the network.
