  Log:
  When suspending a thread if the timeout was very short or
  the system call got interrupted and the absolute timeout is
  converted to a relative timeout, it may happen that we get a
  negative number. In such a case, simply set the timeout to
  zero so that if the event that the thread wants to wait for has
  happened it can still return successfully, but if it hasn't
  happened then the thread doesn't suspend indefinitely. This should
  fix certain applications (including mozilla) that seem to hang
  indefinitely sometimes.
