Sarge xterm scrolling bug, consumes 100% of the CPU!

[Justin Piszcz <jpiszcz@lucidpixels.com>]

I cannot reproduce this error, but the `xterm' in Debian Sarge has a 
serious error.

I am using several xterms to tail -f some log files, after a while, there 
must be some sort of `crap' character that gets printed onto the screen 
and then the xterm scrolls rapidly consuming 100% of the CPU!

I have previously _always_ compiled xterm from source and never had this 
issue, I guess I can try to do that again but my question is in Debian, 
are there some type of special patches applied for xterm?

Any ideas?
