Why use compositonSpecification.xml to specify modules?

[Maoyuxing]

Hi, I read your code and I found that you use a thread in CompositionManager class to wait for modules specified in xml files to connect. If time threshold expires, an error will be thrown. What's the point in doing this? If the core accepts all the modules running on the backends and does not waiting for specified modules, will there be any troubles? Thank you!

The timeout was/is intended to have some other action, e.g. notifying some manager to restart/check the modules, altought without that being implemented the timeout feels ood, I agree.
