Maybe it does, but when I considered this possibility, it sounded
incredible to me that every keystroke would normally interrupt a call
to waitpid.  Aren't there gobs of programs out there who call waitpid
without setting up a loop that checks for EINTR?

But if you say this is the case, then OK.  Thanks for the explanation.
