/me chuckes at self and rummages for O_EXCL flag

Good job, and nice "stuff". Only you weren't on my list of trash talkers.
It's not quite a cryptographic reversal or a overflow exploit for some
unchecked buffer, but it makes a damn good point. In a SUID situation xxt
should most definitely use an exclusive open.

I hearby declare you the winner of the SETUID portion of the trash talker
challenge but do not dub you a trash talker. It doesn't quite fit what I
originally stated, but I think it qualifies. Email me privately and I'll
send you your 50 bucks. I'm a man of my word.  Also I'll still offer 50 to
anyone who can actually reverse the crypto. You've taught me an important
lesson, which I think is this: never resort to trash talking while dealing
with trash-talkers OR never drink a couple of cranvodkas and write email
to a public list. :-)

Is it? Hmm I'll check that out. Thanks.
