        src/sys/kern: kern_condvar.c kern_sleepq.c kern_timeout.c
            kern_turnstile.c sys_lwp.c sys_select.c
        src/sys/rump/librump/rumpkern: sleepq.c
        src/sys/sys: sleepq.h syncobj.h

Log Message:
Ensure that an LWP that has taken a legitimate wakeup never produces an
error code from sleepq_block().  Then, it's possible to make cv_signal()
work as expected and only ever wake a singular LWP.
