Right; I'm just used to that trick being deployed in massively
parallel async event engines rather than linear synchronous code
waiting on a single descriptor. I'm still a bit in disbelief, to be
honest. I'll get over it. Thank you for the note!

Fair enough. I'll work on a patch to disallow it; best case, no one
ever complains, and we've pruned an entire configuration from the list
of things to worry about.

Thanks!
