  Modified files:
    usr.sbin/ppp         main.c sig.c sig.h 
  Log:
  Maintain a `necessary' marker to indicate that we *probably*
  need to process a signal (usually a SIGALRM).  Check to see
  if we need to process a signal both before *and* after calling
  select() as older (pre-2.0) versions of ppp used to.
  
  This handles the possibility that ppp may block at some
  point (maybe due to an open() of a misconfigured device).
  Previously, we'd potentially lock up in select().
  
  The `necessary' marker reduces the increased signal checking
  overhead so that at full speed with no compression transferring
  an 83Mb file via a ``!ppp -direct'' device, we get a 1%
  throughput gain.
