module. This is currently blocked on:
* The external execution mode is faster in some situations, because it avoids
- being bottlenecked on the GIL. We could fix this by moving to a good
- multiprocessing model.
+ being bottlenecked on the GIL. This can hopefully be obviated simply by
+ using --use-processes.
* Some tests in LLVM/Clang are explicitly disabled with the internal shell
(because they use features specific to bash). We would need to rewrite these
* Add --show-unsupported, don't show by default?
-* Optionally use multiprocessing.
-
* Support valgrind in all configs, and LLVM style valgrind.
* Support a timeout / ulimit.
