Scheduler starts before import has finished / pico cyclic dependency problem

When I imported our data into the standalone preview installation, I got a message from pico about a cyclic dependency, see below.

Maybe the scheduler should not run when an import is currently in progress? Any scheduled job, like subscription mails, would probably use invalid/incomplete data?

Not sure if the pico problem only occurs when the import hasn't finished...
