When test on nfs, maybe failed as below:
wait sem0 0: Resource temporarily unavailable
set sem0 0: Invalid argument
exit rmid: Invalid argument
It means getlk routine wait sem0 timeout, because the setlk routine
maybe take too long time on ‘fcntl’ or 'dup'.
So, let wait on sem0 in getlk routine until the setlk routine success
or fail.
