 The sparc test runs are still panicing in the same test case both on
 babylon5 and my own testbed.  The panic message changed from "panic:
 TAILQ_PREREMOVE" to "panic: kernel diagnostic assertion
 "cv_is_valid(cv)" in late March, so maybe there were two different
 bugs and the commit did fix the original one, but since the subject
 line of the PR is still applies, I'll reopen it rather than filing a
 new one.
