        What threads? Why do you call out file FDs different from
        socket FDs?

If you give epoll()/select() a file FD it lies and says the FD is always "ready" even when, as you point out, file operations can block.

My suggestion is to find a real world / production use case for the new reactor so that we can run more than unit / functional tests.

As a "standard" reactor any twisted app would stress-test it for network/pipe operations, no?

For async file I/O my plan would be to export a new IFilesystem (which is closely based on conch.interfaces.ISFTPServer) apps would be have to be written to use it, conch could with minimal tweaking,  and unsurprisingly the SMB server will.

Apps can fallback to thread-based or aio(7) based implementations that already  exists as PoC: https://github.com/twisted/twisted/pull/1420
