I MFC'ed the fix to RELENG_6 last week, but the patch didn't apply
cleanly to RELENG_5.  I tweaked the patch for RELENG_5 and tested it on
a UP box.  I'd like to get some testing on SMP hardware before I commit
it to RELENG_5, just to make sure that I don't destabilize -STABLE.  I
do want to get the fix into RELENG_5, since this thread originated with
a complaint about 5.4-STABLE.
