operating system supports.
Asynchronous means that operations that can normally block your
program (e.g. reading from disk) will be done asynchronously: the
operation will still block, but you can do something else in the
meantime. This is extremely useful for programs that need to stay
interactive even when doing heavy I/O (GUI programs, high performance
network servers etc.), but can also be used to easily do operations in
parallel that are normally done sequentially, e.g. stat'ing many files,
which is much faster on a RAID volume or over NFS when you do a number
of stat operations concurrently.
While most of this works on all types of file descriptors (for example
sockets), using these functions on file descriptors that support
nonblocking operation (again, sockets, pipes etc.) is very inefficient
or might not work (aio_read fails on sockets/pipes/fifos). Use an
event loop for that (such as the Event module): IO::AIO will naturally
fit into such an event loop itself.

This allows module authors to utilise an event loop without forcing
module users to use the same event loop (as only a single event loop
can coexist peacefully at any one time).
The interface itself is vaguely similar but not identical to the Event
module.
On the first call of any method, the module tries to detect the
currently loaded event loop by probing wether any of the following
modules is loaded: Coro::Event, Event, Glib, Tk. The first one found
is used. If none is found, the module tries to load these modules in
the order given. The first one that could be successfully loaded will
be used. If still none could be found, AnyEvent will fall back to a
pure-perl event loop, which is also not very efficient.
