Comment (by dd32):

 [attachment:25660.diff] attempts to cover the Low priority angle of this,
 by hooking into the cron lock transient's actions and re-scheduling the
 update checks to happen in 30 minutes (and +12-ish hours for the next
 normally scheduled check).

 It's completely untested, but attempts to block it delaying twice (over a
 greater than 5 minute period of time, to cover cases where cron is
 triggered is triggered multiple times within a few seconds/minutes). It
 seems like we can probably do that without too much crazy code, and cron
 modifications and is a easy win that's silent to the user.

 Adding a pre-update notification could be nice, however, we'd need to keep
 in mind that it may be 5 minutes before the twicedaily cron that we
 realise that we're going to apply a autoupdate (but, it could also be
 11hrs, 55minutes before hand that we know).
