Does this benchmark open multiple tabs? If so, it needs to retain an
@benchmark.Enabled('has tabs').

I think it does not open multiple tabs, it's a blank page startup after all.

It's hard to me to read the magic in the decorator code, is there any
document/comment/helpmessage explaining what arguments for @benchmark.Enabled
are supported and what effect they cause? can I have bothe @benchmark.Enable and
@benchmark.Disable decorators for one method? Is a native New-Tab-Page on
Android considered a tab in the sense of Enabled('has tabs')?

 class StartupColdBlankPage(benchmark.Benchmark):
   tag = 'cold'
   test = startup.Startup
   page_set = page_sets.BlankPageSet
   options = {'cold': True,
              'pageset_repeat': 5}
 
 
 @benchmark.Enabled('has tabs')
 class StartupWarmBlankPage(benchmark.Benchmark):
   tag = 'warm'
   test = startup.Startup
   page_set = page_sets.BlankPageSet
   options = {'warm': True,
              'pageset_repeat': 20}

Chrome on android doesn't support themes or extensions. Why would it run the
below 4?

sorry, that was mechanical, Undone.
