When array parameters are changed old array 'A' is going to be removed
and new array 'B' is going to be serviced. If array B is raid0 array (takeovered),
array 'A' will never be deleted and mdmon is not going to exit.
Scenario:
1. managemon creates array 'B' and inserts it to begin of active arrays list
2. managemon sets field B->replaces = A
3. monitor: finds that array 'B' is raid 0 array and removes it from list
information about removing array 'A' from list is lost
and array 'A' stays in list forever
To resolve this situation wait with removing array 'B' until array 'A' is not removed.
