[issue6397] Implementing Solaris "/dev/poll" in the "select" module

[Ross Lagerwall]

Ross Lagerwall <rosslagerwall at gmail.com> added the comment:

Is write()ing a devpoll fd a blocking operation in the kernel?
Does it need to have Py_BEGIN_ALLOW_THREADS around it?
The same question applies for open()ing it.

Obviously, the ioctl() call *is* blocking :-)
