A slight change to the way event channels work, but it's incompatible with previous versions. Now ::send and ::receive work the same way for event channels as they do for channels. If you want the event-oriented interface you use ::on, ::once, and ::emit. In particular, you would use :;send instead of ::emit.
Fixed event channel test to match the new interface.
Preparing for change over to setImmediate
Got all the tests working again with the event interface change. Also corrected a few bugs in the process, including the failure to release the clients in the transport.
