Feature #16597: missing poll()
https://bugs.ruby-lang.org/issues/16597#change-84572

* Author: michals (Michal Such疣ek)
* Status: Open
* Priority: Normal
----------------------------------------
When using a socket or a pipe for writing select() cannot determine that the socket is closed. It tells you that it is ready to write but if you don't have data to write you cannot tell that it is in fact closed.

ruby internally uses poll() which can tell when a write socket is closed (without attempting a write()) but presents the broken select() interface.
