Log:
SVN rev 181978 on 2008-08-22 01:17:56Z by jhb
Use sx_sleep() when waiting for a file lock instead of explicitly dropping
the sx lock and then doing a tsleep() without a timeout. The tsleep()
method leads to lost wakeups that can cause processes to hang waiting for
a lock on an unlocked file. The lockf code already uses sx_sleep() in
7.x+.
