AsyncLatch

A construct providing latched, asynchronous execution of side-effecting functions. com.twitter.finagle.util.AsyncLatch#await does not block, but the execution of functions passed to it may be delayed. That is, because the latch guarantees serial, non-concurrent execution, functions passed to await may have to wait until both of the following conditions are met:

1. No other functions are being executed 2. The latch's count is zero

Thus, calling com.twitter.finagle.util.AsyncLatch#incr will cause subsequent functions passed to com.twitter.finagle.util.AsyncLatch#await to be delayed until the count is decremented to zero. Once the count is zero, functions are executed in LIFO order, i.e., the reverse of the order in which they are given to await.
