I see. It should log this so that one can immediately know what is going on there. > Since IDO and the event-handler are single-threaded, this must > complete before the scheduler finally starts and checks get going > again.

In a big installation, this means being blind for several minutes, or one would have to run multiple instances of Icinga, take care not to reload both at once and live with a number of weird issues that need explaining to end users. Is a possibility to keep scheduler and event handler running while the IDO database is rebuilt on the Icinga roadmap?
