Yup. Option 1 was a red herring, I would have had to implement option
2 either way, since it's not signal safe to call execvp() from within
a signal handler.

Hmm, I did get that in some initial phase, but it went away as my
coding got better. Basically, the above means select() returned -1
and errno is EBADF, which would mean the X protocol file descriptor is
incorrect. That's the number returned by ConnectionNumber(), which is
a macro on my system.
Do you have any idea why that happens to you? Are you willing to dig
a little and figure it out?
Cheers,
Richard
