Make the parallelism limit a global instead of always passing it to run_command and finish_command. In the case of an empty command string, try to run any other strings the command may have. Replace JF_BACKGROUND with its sort-of opposite JF_SLEEPQ. Change j->comstring earlier to render JF_RUNQ unncessary. Change the if-else series to a more readable switch statement. Treat IP_STOP_TIMEOUT like a command, calling run_command which then calls term_procs. When the IP_STOP_TIMEOUT "command" finishes, it shouldn't mess with the parallelism limit. Make sufficient checks in finish_command and run_command so that the nonintuitive j->comstring null check isn't necessary to run them. Rename the "waiting" queue to "depend", because the "sleeping" and "runnable" queues are also used to wait for something.
