[PATCH 1/2] do not wake up main loop adding if change is from same thread

[Frediano Ziglio <fziglio redhat com>]

This reduce the frequency the loop is waked up adding and removing
file descriptors or timeouts.
Considering that to support recursion events are removed from list and
added again this reduce iteration number a lot.
