It does not necessarily mean that we should limit > the parallelism of "unit test suite runner" to 1 under prove, though. The current `prove` helper script does not do any separate parallelism, so we are fine in that case, and the new test-tool runner does not currently support running both unit tests and shell tests in the same process, so we should be OK in either case.
