[jochen (gone - plz use gerrit), 2015/03/13 14:39:03]

don't indent in a namespace

what's the unit of time?

[jkarlin, 2015/03/13 18:51:39]

Oddly enough the Blink style guide says that nested namespaces should be
indented.

[jkarlin, 2015/03/15 12:43:10]

Ah, I'm wrong.  "The contents of other nested namespaces should be indented."
but I missed the "other" part, referring to non-outermost.

[iclelland, 2015/03/16 13:09:40]

I'll comment in the code, but all times are in milliseconds. (minDelay,
maxDelay, minPeriod, minAllowablePeriod)

[iclelland, 2015/03/16 13:09:40]

Done.
