- // this class implements the basic interface for supporting multiple
- // profiles. This can be treated either as a circular queue or a
- // linear array of profiles.
- //
- // It is assumed that locking will only be required when a profile list
- // is associated with a STUB_Object. Thus when the STUB_Object accepts
- // ownership of an MProfile it also assumes responsibility for controling
- // access (i.e. locking).
