I have only been able to see this behavior on my system running the
kernel from the 2.4 XFS CVS tree.  It is somewhat reproduceable.

The problem is that I started up a number of "rxvt" sessions and they
took well over a minute to start up.  During that time, the cpu
utilization was almost nil.  (Less than 1%)

There was a background find operation happening, and this seems to be
the key item.

When the problem occurs, does typing sync get everything running again?
I have been seeing an intermittent lock problem with XFS where
everything stops until some other disk activity kicks in and the lock
is released.

I will try that next time it happens.
