| 144 | //Disabled for now. Has a few annoying problems: | ||
| 145 | // * sleepcmd() -> sleep_main(), the parsing of bad arguments exits the shell. | ||
| 146 | // * sleep_for_duration() in sleep_main() has to be interruptible for | ||
| 147 | // ^C traps to work, which may be a problem for other users | ||
| 148 | // of sleep_for_duration(). | ||
| 149 | // * BUT, if sleep_for_duration() is interruptible, then SIGCHLD interrupts it | ||
| 150 | // as well (try "/bin/sleep 1 & sleep 10"). | ||
| 151 | // * sleep_main() must not allocate anything as ^C in ash longjmp's. | ||
| 152 | // (currently, allocations are only on error paths, in message printing). | ||
