commit a9e19b380f9814630018e79b8cafa3c675dd182c
Author: Mark Wielaard <mjw@redhat.com>
Date: Sun Aug 14 23:07:46 2011 +0200
Implement and use select to wait for cmd channel data.
Add a poll implementation to runtime/transport/control.c
(_stp_ctl_poll_cmd) based on the _stp_ctl_ready_q wait queue.
Check whether select is supported in runtime/staprun/mainloop.c
(stp_main_loop) and use pselect with a sigmask that includes
SIGURG to get EINTR notifications whenever an interruptable
event occurred.

runtime/io.c: Explicitly signal setting of _stp_exit_flag.
Call wake_up_interruptible(&_stp_ctl_wq) in _stp_exit()
to signal possible waiters in _stp_ctl_read_cmd().
