*Most significantly, we avoid using setpgid(), because it doesn't work and in fact corrupts the kernel's process group table. *Also, work around tctpgrp() returning garbage instead of 0 on success. This adds an implementation of tcsetpgrp that works by reading the process tables to find a process in the appropriate group. This isn't used for the main job control operations, though, since it might be relatively slow. At this point, basic job control seems to work.
