I guess I trimmed the original article too much, as yours is the second
response I've seen that said this.  The original poster (who,
unfortunately, didn't put a "Subject" line in his message, so readers may
be having trouble finding it) mentioned this, but dismissed it as
distasteful.  Personally, I think it's better than my ptrace-based
solution, as it is really simple and completely portable; in fact, I was
sort of hoping that my description of the complexity of implementing it
without a temp file would cause him to accept the temp-file solution.
