This was exactly how I fixed it to begin with but then discovered that I
got into an infinite loop where select would always return a bad status
complaining about a bad file-descriptor. Zeroing the fd sets on bad status
got rid of this problem. But I'll continue to watch out for it.
Also, as you know, I've modified our fdManager.cc to use VMS event flags
so that I can wait on a bunch of event flags (one for the timers, one for
the select, and one for my VMS mailbox) instead of being stuck in
select (I added select qios that use an AST to set the select event flag)
so I could still have an outstanding bug.

Thanks Jeff. I know you get a lot of interruptions from us all!
