- Rename files timer.* to posix_timer.*. - Reimplement using an OS timer rather than a handcrafted wait loop. - Use a Slim R/W Lock for synchronization. - Drop timer chaining. It doesn't server a purpose since all timers are local only. - Rename ttstart to itimer_tracker to better reflect its purpose. It's not the anchor for a timer chain anymore anyway. - Drop fixup_timers_after_fork. Everything is process-local, nothing gets inherited. - Rename timer_tracker::disarm_event to disarm_overrun_event for better readability. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
