Detailed Description

Wait points that blocks the execution of a thread at a specific code point until an event occurs.

The cb_waitpoint mechanism bundles the pthread_cond with pthread_mutex to ensure thread safety and re-entrant blocking mechanism. Ideally, when pthread_cond is used, it is always required to guard its access with pthread_mutex. This waitpoint abstracts the use of pthread_cond and pthread_mutex into single waitpoint structure.
