Yes... although I wasn't really proposing to go to that much trouble,
since this scenario seems uncommon enough not to be worth it. I see
you've gone ahead and done that, so kudos.

D'oh! That was certainly poorly tested. It kind of worked for me,
without me fully understanding why at the time. Looking more closely
at how perl opens a pipe, I see it seems to always succeed, even when
the pipe components fail. Looks like testing for emptiness of the
file handle would do the trick.
