Restarting apache shouldn't bother mysql. At least, no more than rebooting the machine would. On second thought, though, I don't think it's necessary. Apache should drop the connections in less than a minute. After that, the connections will stay in the TIME_WAIT or FIN_WAIT state for an amount of time, maybe 5 minutes, depending on your kernel.
