In Java, a(n)________ is a queue of threads waiting to reenter the monitor for an object.

Monitors implement ________ between threads of execution.

Which type of monitor allows a thread inside the monitor to signal that the monitor will soon become available, but still maintain a lock on the monitor until it exits?

________ is important for preventing indefinite postponement in the readers/writers problem.

Monitor initialization ________.

In the readers/writers problem, cascading in readers ________.
