> Please upgrade to 1.5.9 and/or the latest snapshot to see if either help.

Thanks for the response; unfortunately upgrading did not help. I still
don't know what triggers the behaviour, and it may be over an hour of
use before the problem occurs, but when the CPU hits 100%, xemacs and
each instance of bash are involved.

Is it simplistic of me to wonder if there's a regression to the bug to
which this URL refers?

http://www.cygwin.com/ml/cygwin/2000-04/msg00522.html

Or perhaps there are many plausible ways in which the symptoms I've
described can occur(?)

Thanks again,
Graham
