Funny source code tells me IOCP is used;
proactor is only implemented on Windows with IOCP.
https://github.com/python/cpython/blob/3.12/Lib/asyncio/proactor_events.py
But maybe the focus is more on networking than file system.
But it has sock_sendfile() that might avoid copying data to userspace.

The docu tells me:

loop.add_reader() and loop.add_writer() only accept
socket handles (e.g. pipe file descriptors are not supported).
https://docs.python.org/3/library/asyncio-platforms.html
Alternatives are aiofiles and anyio and maybe more,
but not sure whether they span all platforms, i.e. unix,
windows and mac or whether they have similar restrictions.
Theoretically on Windows IOCP should also cover file handles:

Its use by libuv the basis for node.js.
