hmm - officially the kernal has no bugs.  In practice, its behavior alters
from one snapshot to the next.  But #243314 is perhaps related to this.
Mostly I've been using the 2.4.18, etc.  (I did some testing for a 2.6.4
kernel but didn't see the problem as reported, but it's on my list until
I have a large enough time slot to finish rewriting a chunk of xterm to
better handle bursts of output).
