The developer of a project that uses one of these libraries has to periodically check for an update, apply it to their software, and redeploy or redistribute their software. The library vendors usually can't initiate this process until an official tzdata release posted at IANA.
Our lead time should not be instantaneous, but we shouldn't wait till the last possible minute either. Somewhere in the middle is prefered.

(Thanks to localtime() not working that way, a reboot shouldn't be necessary unless there are long-running processes using ICU *not* associated with a user session.)
