sleep()

[Richard Carling]

  In 4.1c there should be an fsleep() call available.  This uses
sixtieths of a second as a parameter instead of seconds (so pass it a
60 instead of a 1).  It does not use signals but the kernals sleep-wakeup
mechanism.  If your having problems or want something with a little finer
granularity you might want to try it.  I never understood why it wasn't
part of unix from the start.
