Not everybody uses the async support. This was a good change, and I'm 
taking advantage of it in at least one external package.

I wonder how hard it would be to fix the async support not to be 
hindered by it.

Also note that that this form could be useful for the asynchronous route 
as well: after the user has send some new input, we don't really want to 
process the "old" eldoc requests anymore, those responses should be ignored.
