[cfe-dev] Concurrent AST traversal with libTooling

I'm using libTooling to parse and traverse the ASTs of full
compilation databases using a RecursiveASTVisitor. I have attached a
small example of how my tool is structured (a modification of
http://clang.llvm.org/docs/RAVFrontendAction.html to use a compilation
I would like to be able to parse each TU and traverse the AST on its
own thread so that I can process multiple TUs concurrently.
Would this be possible with libTooling and tooling::ClangTool as
currently implemented and used in my example? Give the implementation
of newFrontendActionFactory<> I feel like it likely isn't.
If not, the only way that I can currently see this being possible is
by spawning up multiple threads that would each call
tooling::runToolOnCodeWithArgs(), and handling the compilation
database manually. Would this be safe to do with the way clang and
libTooling is currently implemented?
