Hi,
	First an emacs I was running from another machine was doing ^N's
indefinitely.  I could press keys and they would be acted upon correctly,
and then the ^N's would continue.  Eventually the ^N's stopped.
	Shortly thereafter, the mouse pointer started warping roughly
7-8 character widths due left at irregular intervals, even with the mouse
completely still and my hands off it.  This was happening a couple of times
a second, then a spurt every couple of minutes.  Even when the mouse warps
somewhere else in the same window, keystrokes I happen to make at the
time of the warp are lost.  The warp can happen with the mouse pointer
in any window, including the root window.
	On athena, I had two xterms going, no applications, and one of the
xterms was rlogin'd to another machine.  I had "xhost +" to give access to
that other machine.  Since bogus X events generated by someone on the other
machine could theoretically cause this behavior, I checked, found that no
one else was logged on to the other machine and no unusual processes were
listed with "ps".  I did "xhost -" and the warp problem continued.  There
also were no unexpected processes running on w20-575-75.
