NAME
       Coro::RWLock - reader/write locks

SYNOPSIS
	use Coro;

	$lck = new Coro::RWLock;

	$lck->rdlock; # acquire read lock
	$lck->unlock; # unlock lock again

	# or:
	$lck->wrlock; # acquire write lock
	$lck->tryrdlock; # try a readlock
	$lck->trywrlock; # try a write lock

DESCRIPTION
       This module implements reader/write locks. A read can be acquired for read by many coroutines in parallel as long as no writer has locked
       it (shared access). A single write lock can be acquired when no readers exist. RWLocks basically allow many concurrent readers (without
       writers) OR a single writer (but no readers).

       You don't have to load "Coro::RWLock" manually, it will be loaded automatically when you "use Coro" and call the "new" constructor.

       $l = new Coro::RWLock;
	   Create a new reader/writer lock.

       $l->rdlock
	   Acquire a read lock.

       $l->tryrdlock
	   Try to acquire a read lock.

       $l->wrlock
	   Acquire a write lock.

       $l->trywrlock
	   Try to acquire a write lock.

       $l->unlock
	   Give up a previous "rdlock" or "wrlock".
