| The real problem is that UNIX signals are utterly inadequate and

| program to work without race condition problems.  This should have been

  Which version of UNIX are you talking about?  Even System V has
reliable signals these days (albeit 4.1BSD signals).  If you're having
race condition problems on any modern UNIX, they're in your code, not the
OS.

  I will admit that the 4.1BSD signal facility found in System V is
uglier than mud and extremely difficult to use for complex interaction
with multiple signals.  The signal facility that was introduced with
4.2BSD is *MUCH* nicer.  I will never understand why AT&T went with the
4.1BSD signal facility when they finally decided to put reliable signals
into System V.  I can only guess severe and total brain damage.
