I have been using libevent in multithreaded code, where more than one event queue is used (i.e. event_init() is called multiple times,) and was bitten by the fact that current_base is updated on each call to event_init(). This becomes a problem when attempting to use the evhttp support in such an environment, which does not support explicit event_base specifications.
The attached patch only initializes current_base to the first one created so that the behavior is at least predictable and controllable. -- paul
