… (the true) creation of the underlying buffer. Initialization of an already intialized mutex or condition variable may result in undefined behavior. In the context of multiple users one 'creates' and others 'open'. This allows differentiation similar to the contructor taking DataElementFile as argument.
…ition variables are properly initialized before first use.
The typical use case is inter-process, but it allows for multiple threads within a process as gettid() is unique over all processes.

Although explicit specification may be preferred, implicit is apparently the accepted use case.
While (looped) waiting on condition variable in 'Sync()' the time out triggers an 'abort()'.
- Unresponsive child processes are 'killed' after a set timeout. - Disable ASSERT triggers in 'test_cyclicbuffer'
It is unintuitive that the anmount of data is always 1 less than the (maximum) size.
The condition prevents checking an invalid state after construction. Moreover, the invalid state condition is part of the return value, and, identical ASSERTs are used throughout the code where the invalid pointer may be used.
