A nice clean way to handle this would be to have the signal-handling
routine's return code indicate whether the system call which was
interrupted, if any, should be restarted.  This would still require
changes to old code which doesn't return anything meaningful from
the signal handler.  Maybe yet another flag, specified in the call to
signal that gives the handler's address?
