Is there a way to portably use signal (or something else) to
wake up a select call?  And can anyone tell me what the
execptfds fields are (do they map to signal numbers? drool, drool!)
In our application we just need to wake up the select call, but can't
afford to lose an IPC "poke," so if there is not sure way to avoid
this with signals (which seems to be the case, so far as I can ascertain)
then we will have to find something else.  Thanks for any help---the
manual pages are lacking, and the Advanced Unix Programming book I 
have is old!
