    //
    // Support for JVMTI tracing code
    //
    // ------------
    // Usage:
    //    -XX:TraceJVMTI=DESC,DESC,DESC
    //
    //    DESC is   DOMAIN ACTION KIND
    //
    //    DOMAIN is function name
    //              event name
    //              "all" (all functions and events)
    //              "func" (all functions except boring)
    //              "allfunc" (all functions)
    //              "event" (all events)
    //              "ec" (event controller)
    //
    //    ACTION is "+" (add)

    //              "t" (event triggered aka posted)
    //              "s" (event sent)
