In concurrent programming a critical section is a piece of
code that accesses a shared resource (data structure or

have to wait a fixed time to enter it (aka bounded waiting).
Some synchronization mechanism is required at the entry and
exit of the critical section to ensure exclusive use, for
example a semaphore
