Warn if forked from the event loop during event_reinit()

Browse Source 
Calling fork() from the event loop is not a great idea, since at least
it shares some internal pipes (for handling signals) before
event_reinit() call

Closes: #833
(cherry picked from commit 497ef904d544ac51de43934549dbeccce8e6e8f8)
