Unfortunately, it appears that asyncore and asynchat are caught in a
deadlock, in which it is demanded that certain patches be applied before
any further work is done, but nobody (even among those making the
demands) is both willing and able to review and apply those patches.

We need this situation to be resolved, preferably by somebody with
commit access doing the necessary work, but failing that by allowing new
patches and requiring the old ones to be updated at whatever time
somebody decides to actually address them.
