Comment 5 for bug 1204123

As a refinement to the above awesomeness, I'd like to propose:

 -a graceful_shutdown -s <service>
 -a graceful_shutdown_perl
 -a graceful_shutdown_c
 -a graceful_shutdown_all

 -a deregister -s <service>
 -a deregister_perl
 -a deregister_c
 -a deregister_all

 -a reregister -s <service>
 -a reregister_perl
 -a reregister_c
 -a reregister_all

as convenience options to "-a" that use "-k <value> -a signal" appropriately. I think not having to remember signal mapping would be a big help in usability.
