Re: [bug #60774] make hangs on fcntl lock when using -O and stdout is /dev/null

The point is that only /dev/null *should* be shared. Any other file *might* be 
locked by an unrelated process but that would represent an error condition in 
which incorrect results should be expected. I can’t think of a file other than 
/dev/null which would appropriately be shared with unrelated processes in a “w” 
(write) condition.
