$ man flock(3)
     Requesting a lock on an object that is already  locked  nor-
     mally  causes  the  caller  to  block  until the lock may be
     acquired.  If LOCK_NB is included in  operation,  then  this
     will  not  happen; instead, the call will fail and the error
     EWOULDBLOCK will be returned.

$ perldoc -f flock
             releases a previously requested lock.  If LOCK_NB is
             added to LOCK_SH or LOCK_EX then flock() will return
             immediately rather than blocking waiting for the
             lock (check the return status to see if you got it).
