devserver: generalize lock dictionary; substitute multiprocessing for threading
* Migrate the lock dictionary functionality into a dedicated class, so
it can be easily used with other sets of resources.
* Replace multiprocessing primitives (processes, locks) with threading
equivalents. There's no apparent reason for using multiprocessing, and
threading primitives are expected to be faster/lighter.
