sorry, it's not what I want to say. This isn't so serious.
Our colleagues are doing a lot of various tests every day,
so they can find some unexpected behaviors which are not the direct requests
from the certain customer.
But it would be advantageous if these behaviors could be fixed soon when we
promote Pacemaker and Heartbeat (or OpenAIS) to some potential customers.
It's true that if the customer doesn't need that function, that's not a bug.

well, whatever, beer and pizza are really magic wands :)

Thanks,
Junko
