 pengine_event_loop(:Closure, +Options) is det
Starts an event loop accepting event terms sent to the current pengine or thread. For each such event E, calls ignore(call(Closure, E)). A closure thus acts as a handler for the event. Some events are also treated specially:
create(ID, Term)
The ID is placed in a list of active pengines.
destroy(ID)
The ID is removed from the list of active pengines. When the last pengine ID is removed, the loop terminates.
output(ID, Term)
The predicate pengine_pull_response/2 is called.

Valid options are:

autoforward(+To)
Forwards received event terms to slaves. To is either all, all_but_sender or a Prolog list of NameOrIDs. [not yet implemented]
