Rainer Gerhards cd51ae3647 core: enable internal messages at any time
previous code could deadlock if internal messages were issued
inside queue processing code, which effectively limited
error-reporting capabilities. This change makes it possible
to call error messages from any part of the code at any time.
This comes at the price of slightly delayed message output.
