This was fixed on HEAD in revision 1.48 (March 13th), with the comment
"MFC: 1 week".
The commit to RELENG_7 did not happen until April 19th, see revision
The PR referenced in the CVS commit is PR 117603.
David, can you verify you're using a version of
src/sys/kern/subr_sleepqueue.c that is 220.127.116.11 or newer?
If so, the problem David is experiencing is different. If not, David
will need to csup and then rebuild world and kernel (do NOT just do
one; do both) to pick up the changes.
