   * A ThreadSlice represents an interval of time on a thread resource

   *
   * ThreadSlices are typically associated with a specific trace event pair on a
   * specific thread.
   * For example,
   *   TRACE_EVENT_BEGIN1("x","myArg", 7) at time=0.1ms
   *   TRACE_EVENT_END0()                 at time=0.3ms
   * This results in a single slice from 0.1 with duration 0.2 on a
   * specific thread.
