Bug Description

The ceilometer-polling service cannot start on Windows due to the new usage of the cotyledon library, which tries to set and call Linux-specific attributes and functions, one of which is os.setsid().

@Claudiu Belu: I have released a new cotyledon (1.6.0) and it should be window compatible. Can you confirm ?

@Mehdi: Thanks for your interest in having Windows support. Using multiprocessing instead of forking doesn't help either as the service object that we're trying to pass to subprocesses isn't pickleable.

    Windows: avoid passing conf objects to subprocesses

    On Windows, cotyledon uses multiprocessing instead of forking. Meanwhile,
    config objects as well as service manager objects aren't pickleable.

    For this reason, we'll avoid passing unpickleable objects to subprocesses,
    making all the required initialization on the subprocess side.

    This change will allow ceilometer-polling to run on Windows.
