+// emitting multiple errors is not supported by stream.
+//
+// I do not think that this is a good idea, at least, there should be an option to pipe to 
+// continue on error. it makes alot ef sense, if you are using Stream like I am, to be able to emit multiple errors.
+// an error might not necessarily mean the end of the stream. it depends on the error, at least.
+//
+// I will start a thread on the mailing list. I'd rather that than use a custom `pipe` implementation.
+// 
+// basically, I want to be able use pipe to transform objects, and if one object is invalid, 
+// the next might still be good, so I should get to choose if it's gonna stop.
+// re-enstate this test when this issue progresses.
+//
+// hmm. I could add this to es.connect by deregistering the error listener, 
+// but I would rather it be an option in core.
