The thintarget query can 5-20 seconds on average and will only increase in time as more targets are converted. We should move the generation of this information into the bazel build itself, and output a file from the bazel build for scons to consume. This may be possible with the built in genquery rule or some custom rule that can find all the targets scons would care about, which is the current set of ThinTargets currently generated from the external aquery call.
