 *    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.
