Maybe the scheduler could indeed check in which interval it is being run
in the cronjob and offer a warning for tasks that won't be able to be
executed "in time" because of it. A feature for 4.4. Would that be possible?

I agree with Francois. It is nice the way it is, and a TYPO3 hoster will
know how to set up the cronjob for the scheduler, if this service is
provided to its customers. And you could probably create a wrapper shell
script to call the scheduler and add that as your cronjob if the hoster
doesn't allow you otherwise.
