Also don't forget twisted.runner.procmon and twistd procmon - it
hasn't got all the features of supervisord, but it may be enough. eg
twistd --logfile=procmon.log --pidfile=procmon.pid procmon \
twistd --logfile=web.log --pidfile=web.pid -n web --path .
$ twistd procmon --help
Usage: twistd [options] procmon [procmon options] commandline
-t, --threshold= How long a process has to live before the death is
considered instant, in seconds. [default: 1]
-k, --killtime= How long a process being killed has to get its affairs
in order before it gets killed with an unmaskable
signal. [default: 5]
-m, --minrestartdelay= The minimum time (in seconds) to wait before
attempting to restart a process [default: 1]
-M, --maxrestartdelay= The maximum time (in seconds) to wait before
attempting to restart a process [default: 3600]
--help Display this help and exit.
procmon runs processes, monitors their progress, and restarts them when they
procmon will not attempt to restart a process that appears to die instantly;
with each "instant" death (less than 1 second, by default), it will delay
approximately twice as long before restarting it. A successful run will reset
