The k_poll signal and event code is reworked a bit such that signal is raised and event is processed only when appropriate. We want to avoid changing the internal of event and signal objects at the same time we try to raise the signal (which changes the internal states too). In addition, print out some information on how many signals raised and received to indicate we are actually switching all related threads.
