This may be not a problem of this CL, but doAction changes config and
worker.onMessage. Calling it more than once looks dangerous.
How about setting worker.onmessage in a separate function (initWorker for
example)?

[hiroshige, 2015/09/07 07:29:55]

Done, created separate |config| for each doAction() call.
Yes, pywebsocket side should be refactored (and started refactoring but will
take some time and I don't want the refactoring to block this CL).
