Yes, several times...  If you start a background process that is nohup'ed,
and it writes sporadic output, the pty will recieve that output until the
program dies, as far as I can tell...  An occasionally useful feature, I
might add.  (To kill the dxterm that's on that pty and start an xterm with
a more useful scroll bar.)
