 // events to some other universe, you can copy-and-paste this file as well as
 // trace_event.h, modifying the macros contained there as necessary for the
 // target platform. The end result is that multiple libraries can funnel events
 // through to a shared trace event collector.

 // Without the use of these static category pointers and enabled flags all
 // trace points would carry a significant performance cost of acquiring a lock
