Thanks for the response.
Maybe we can, as a start, consider how to extend the mode of the command
server. Currently I instantiates it with mode='pipe' and overwrites
every channel.

and 'chg serve' won't terminate the server...

Wow, thanks. I'm yet tried test-mq.t.
BTW, doesn't it create and leave bunch of background processes?

  % ps aux | grep 'hg serve' | wc -l
  22

Maybe I need to shutdown them automatically in order to run whole test
suites.
