Great news!  I can no longer reproduce this problem; moreover I can't
yet reproduce *any* other problem with LFS.

I currently have running:

 - 2 rsyncs copying and then deleting pkgsrc in a loop
 - 2 pax's making hard-link trees of the above pkgsrc copies
 - 2 cleaners (the mount one, and a manual -c -d)
 - 2 postmarks running 50million transactions each

on a nearly-full filesystem (that has previously been filled several
times)

Nothing appears to be breaking!  I am.. thrilled. (It's getting pretty
slow for some of the writing processes at points, especially with both
cleaners going the disk is doing a *lot* of reading, but it is Still
Going!)

This is clearly only preliminary testing, and hasn't been running all
that long - but already much longer than previous such tests.=20

This lfs is in a vnd over a cgd ffs, fwiw.

It doesn't yet mean LFS is ready for real use; but for the first time
it seems worth trying to really find out. It indicates to me that more
rigorous and prolonged testing is now clearly worthwhile; I shall be
setting up a system to leave thrashing full-time like this, and
hopefully others can do likewise. =20

My fulltime test machine will be lfs over raidframe R5 on ide (no vnd)
on a multiprocessor.

Thank you so much for all your LFS work, especially recently.  It
seems to have made a very big difference.
