[Mini-OS] Fix domain blocking race

A callback which wakes a thread may happen between the moment
schedule() gives hand to the idle thread and the latter blocks the
domain.  Idle hence needs to atomically check that no thread is
running and block, else awoken threads may have to wait up to 10
seconds.
