Feature or enhancement

Proposal:

ppoll is an extended version ofpoll that lets you set the timeout with nanosecond precision (it also supports setting a signal mask, but that's not important right now). It's available onLinux,FreeBSD,OpenBSD,NetBSD, and probably other Unix-likes.

It would be useful if the Pythonpoll function would transparently useppoll on systems where it is available to provide timeouts with nanosecond precision (as opposed to the default millisecond precision).

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
