  Log:
  Fix msgsnd(3)/msgrcv(3) deadlock under heavy resource pressure by timing out
  msgsnd and rechecking resources.  This problem was found while I was running
  Linux Test Project test suite (test cases: msgctl08, msgctl09).
  Change `msgwait' to `msgsnd' and `msgrcv' to distinguish its sleeping
  conditions.  Few cosmetic changes to debugging messages.
