The select module already supports the poll() system call. Or is there a special variant that only Solaris has?

I think Jesus refers to /dev/poll—i.e., the interface for edge-triggered polling on Solaris. This is the Solaris equivalent of FreeBSD's kqueue and Linux's epoll. -- Alexandre

Yes. In python 2.6, Linux and *BSD benefice of access to high performing "poll"-like interfaces, non portable. Solaris has "/dev/poll" too, so we can provide another non-portable interface :). In fact I think it could be interesting to investigate the direct use of "/dev/poll" in Solaris under "select.poll" implementation, if available, in a transparent way. With this could be possible to improve efficiency without adding another non-portable interface.

But before investigating options, I want to know if there is interest on it. I think so, because Solaris/OpenSolaris is an important platform, I will take care of the code, and we already have non-portable interfaces: "select.epoll" for Linux and "select.kqueue" for *BSD.

+1 I'm sure *Solaris users would appreciate this. Go for it.
