-------------------------------------------------------------------------
Loading of CDI model is implemented through build. That means that build method can be
invoked from different threads, one requesting for loaded model, the other performing
Eclipse's build. We had already met synchronization problems caused by concurrent
access to build, and tried to solve it with improving thread safety. Now, I think, we just
cannot allow for concurrent build to happen. One build should wait for the other.
