No, calling a protected *procedure* is not potentially-blocking (unlike
calling a protected *entry*). If your compiler has ceiling_locking by
defauly you may have to adjust the priority, though.

Nothing, since I don't know what was a problem with your original
design. As far as I understand, it's the mere fact of calling an entry
of a protected object that serves as interrupt handler, with a priority
in Interrupt_Priority range. So I don't think that moving the logic
would change anything, as long as you still call the entry;
