[New-bugs-announce] [issue27634] selectors.SelectSelectors fails if select.select was patched

[Przemyslaw Wegrzyn]

New submission from Przemyslaw Wegrzyn:

The SelectSelector makes a local copy of select.select() built-in and calls it via self._select later on. It no longer works if select.select() built-in is replaced with function (something gevent's monkey patching does).

Currently gevent employs a workaround - it overwrites SelectSelector._select. It wouldn't be necessary if SelectSelector could cope with select.select() being a regular function.

Attached is a file reproducing the issue.
