[issue29717] `loop.add_reader` and `<<EOF`

[Andrew Svetlov]

Andrew Svetlov <andrew.svetlov at gmail.com> added the comment:

If fd is a regular file it is not supported well by all select/poll/epoll.
Registration may succeed but the data is marked as "already ready for reading".

Not sure if we should do anything.
The situation may be changed after eventual providing asyncio API for files (there is no actual work for it yet).
