BUG#: 9013
TITLE: Indications arrives out-of-order from provider to handler service
DESCRIPTION: Enhanced deliver() API to wait until indication arrives to the HandlerService. HandlerService gurantees the indication delivery order. This ordering is automatically enabled with PEGASUS_ENABLE_DMTF_INDICATION_PROFILE support is defined.
