In the short term I'm happy with it too.

But I seem to remember that last time this issue came up the
suggestion was to use highres timers.  Someone tried but they did an
amazingly poor job so the effort just died off.  It takes someone with
some skill because highres timers operate with different context
requirements than normal timers.
