switch from System.Cmd.Utils to System.Process
Test suite now passes with -threaded! I traced back all the hangs with -threaded to System.Cmd.Utils. It seems it's just crappy/unsafe/outdated, and should not be used. System.Process seems to be the cool new thing, so converted all the code to use it instead. In the process, --debug stopped printing commands it runs. I may try to bring that back later. Note that even SafeSystem was switched to use System.Process. Since that was a modified version of code from System.Cmd.Utils, it needed to be converted too. I also got rid of nearly all calls to forkProcess, and all calls to executeFile, which I'm also doubtful about working well with -threaded.
