105 * If 'group' is not NUL, the jobs queued with a same value (as the pointer value 'group')

107 * If 'timeout' is not 0, it represent the maximum execution time for the job in seconds.
108 * At first, the job is called with 0 as signum and the given argument.
109 * The job is executed with the monitoring of its time and some signals like SIGSEGV and
110 * SIGFPE. When a such signal is catched, the job is terminated and reexecuted but with
111 * signum being the signal number (SIGALRM when timeout expired).
113 * Returns 0 in case of success or -1 in case of error.
