Classes of locks

In this chapter, we only discuss the simplest kind of lock: one which can be acquired by a single thread and later released by the same thread, and can only be owned by a single thread at a time.

There are other classes of lock with slightly different semantics, such as:

Recursive Lock: A recursive lock can be claimed many times by a single thread and then has to be released as many times as it was claimed. It can clearly be implemented relatively easily as a wrapper around any of the basic locks we discuss.
