The option `-misched-detail-resource-booking` prints the following
information every time the method
`SchedBoundary::getNextResourceCycle` is invoked:

1. counters of the resources that have already been booked;

2. the values returned by `getNextResourceCycle`, which is the next

available cycle in which a resource can be booked.

The method is useful to debug low-level checks inside the machine
scheduler that make decisions based on the values returned by
`getNextResourceCycle`.
