4One thread modifies the readCounter and the other thread modifies the writeCounter.

6TODO The internal low-level implementation might be merged in some form with audio_utils fifo
7and/or FMQ [after confirming that requirements are met].
8The higher-levels parts related to AAudio use of the FIFO such as API, fds, relative
9location of indices and data buffer, mapping, allocation of memmory will probably be kept as-is.
