Sorry, but don't use this patch.
The setsid call makes things slightly better but if Shepherd prints
anything (for example, a service's status update), it will crash
(IIRC) because stdout still references the terminal. Ideally,
exec-command (from the same file) could be used to also close the open
file descriptors (including the terminal's) but that's done too late
and would also close the control socket (and probably other important
