When exactly does it start to hang? If you trigger completion? Is it
reproducible? The communication with the backend is asynchronous, it
shouldn't block the UI. Are you sure that the blocking does not occur
with the built-in code model for the same code and the same use case?

Please provide answers to this questions in a bug report.

The current focus lies on proper/usable highlighting, diagnostics and 
completions from clang. Later indexing will be addressed, but that's 
another story. For concrete questions, just ask.

Again, the best you can do is to create proper bug reports.
