Speaking of which, if it'sthe same repeated characters problem I saw I've been
meaning to look into that (since I can reproduce it easily), but I just
haven't had time due to day-jobness.
I wsa under the vague impression that we were doing a write() into a pipe
somewhere that was doing a partial write and returning, and the retry code
wasn't skipping the already written bit when it retried the write. (Could be
wrong, but it matches the behavior I saw. If the xterm it's writing into
can't take data for a bit because the system's gone all swap happy, that's
when I see the repeats...)
Dunno if this is the problem you've been seeing...
