Yeah, so I think burst-profiling is basically still a single-event 
profiling mode - with a tooling-side filter that skips the long-periods 
and includes the burst-periods, and transforms all the statistics and 
counts to make sense in the usual perf context.

Ie. I don't think it should be overly intrusive, and it could be a nice 
performance & profiling quality feature we'd consider using by default 
eventually.

Thanks,
