Description

Some embedders, and perhaps someday, the UIMA framework itself, want to take a set of primitive analysis engines in some flow, and initialize them in parallel, on a multi-core machine, where the AEs share a resource manager, and even (for scaled -out instances) a common UIMA - Context.

Add the minimal synchronization and ConcurrentMaps, etc., to permit this, in order to reduce initialization time in multi-core deployments.
