package sys.thread

Creates a new condition variable. Conditions variables can be used to block one or more threads at the same time, until another thread modifies a shared variable (the condition) and signals the condition variable.

A Deque is an output-restricted double-ended queue with a pop method that can block until an element is available. It is commonly used to synchronize threads.

A Lock allows blocking execution until it has been unlocked. It keeps track of how often release has been called, and blocks exactly as many wait calls.

Creates a mutex, which can be used to acquire a temporary lock to access some resource. The main difference with a lock is that a mutex must always be released by the owner thread.

Creates thread local storage.
