If the value isn't sensible as a GC name the test will very likely fail because of an invalid CLA to the subprocess.  And validating that it's a valid GC name involves using vm.gc.GC, which brings in WhiteBox and all its attendant cruft.

Okay, but is it not better then to skip the string concatenation part and give the complete flag directly as an argument to the driver directive?
