Reeeeeely!  I assumed it was just me, as I have an old-ish
self-compiled bash in a highly nonstandard environment.

I have the symlink, but my process-substitution-happy shell scripts
started breaking this way, recently, as well.

Mine die, suggestively, at /dev/fd/63.  They don't /always/ all die; but
somehow, I crossed some kind of rubicon and now they do all die.  If
I carefully smell the air afterwards there is the faint odor of scarce
OS resources leaking.  (Just kidding about that last part :P)

Haven't been able to clear out the process table or generally to
"get all diagnostic" on it yet; it's on my list but I really
must finish some paperwork for a certain government agency.

I'll get back to the list with whatever I can figure out about
this sometime soon.
