## Detailed Description

Default implementation of the IIncidentSvc interface.

This implementation is thread-safe with the following features:

- Calls to fireIncident(), addListener() and removeListener() are synchronized across threads.
- Calls to IIncidentListener::handle() are serialized, i.e. at any time there is at most one incident handler being executed across all threads.
