The most likely problem is that I overlooked a problem with gpm in ncurses 
which allowed it to open an unwanted connection for xterm.  (For quite a 
while this wasn't a problem since gpm and X wouldn't work together, but 
finally X was fixed, and packagers began turning on gpm without asking 
anymore).

The connections aren't closed, and after a few tries, the application 
becomes unusable.  It's still a problem with CentOS iirc, since I fixed it 
in ncurses with its 5.6 release - looks like CentOS 5.6 has the previous 
release for ncurses still (more than five years old).  I can lookup the 
exact versions later, but am short of time this morning.
