Hmm. It looks like this arc4 RNG is used just for generating a unique
"X-TUID" header. Which seems to be used in isync (from which imap-send
is derived) to be to avoid duplicates in synchronization. But imap-send
doesn't actually use it for anything, as it just blindly pushes the
messages.

In other words, should all of this TUID code (and the arc4 code) simply
be ripped out?
