* Interaction with AIO as a subsystem, rather than actually issuing AIO
*
* This header is for AIO related functionality that's being called by files
* that don't perform AIO, but interact with the AIO subsystem in some
* form. E.g. postmaster.c and shared memory initialization need to initialize
* AIO but don't perform AIO.
