This sounds like a solution then... in pseudo code
while true
send shutdown to mysql
wait 5 seconds
if mysql still running
if runlevel not in (0,1,6)
# manual stop, not reboot/halt
if 30 seconds has passed
report to user that mysql will probably die and restart
start again # will respawn mysqld when it does die
else
log warning about waiting forever to reboot/halt..
else
break # service is dead
