These routines are simple plugin replacements for the file_* routines in disk.c . They back-end into the POSIX AIO routines to provide a nice and simple async IO framework for COSS.

AIO is suitable for COSS - the only sync operations that the standard supports are read/write, and since COSS works on a single file per storedir it should work just fine.
