…iftlang#9243) Add an operation queue around execution of swiftPM process execution. **swift-testing** based test will run all tests in parallel at the same time, causing each invocation to spawn a process which will then spawn many other subprocesses. This is compounded by tests that use arguments, as each combination will create another test that will run in parallel. These leads to a process bomb consuming all CPU and causes massive I/O blocking. Add a limit to how many swiftPM top level processes can run at the same time during testing. This is similar behaviour to XCtest based testing with the **--num-workers** option limiting the number of occurrent tests.
