I don't know.  I think `xterm -C' is better than either one, if it can
be made to work properly.  (I have held off on updating to latest
-current in the hope that this might be resolved one way or the
other.)

This is a well-know bug in printf(9).  The TIOCCONS ioctl always gave
non-deterministic crashes.  Now it gives determinstic panics when
pintf() is called while sched_lock is held.  Work-around: don't use
anything that uses TIOCCONS (xconsole?).
