Looks like the existing --cwd option is close to what I need, but it has 
effect only on one command. I need a way to permanently change a working 
directory of a running instance of command server.

Maybe add a flag to not restore cwd after command ends ? That way I 
could set it once and do not pass for every command.

Also, there is a known issue on a cmdserver wiki page "server doesn't 
notice changes to hgrc files". Do you know, is there plans to fix it 
anytime soon ?
