I discussed the concurrency issue with some folks who work on libTooling, notably Sam McCall & Dmitri Gribenko. This was the approach they suggested I follow. LibTooling also provides some nice mechanisms for curating compiler options, which is possible, but less than ideal to reimplement in a python script. There are probably more benefits that escape me at the moment, but that was the first one I thought of.

Out of curiosity, if the concurrency issue was fixed in the compiler and the python script was removed/deprecated, would you still feel the same way?
