Remove these two constants (IS_SINGLE_PAGE_APP, ITEM_SELECTOR). You don't need
them.

Done.

[petrcermak, 2016/08/25 09:57:19]

instead of calling DumpMemory directly, please do the following:

if self._take_memory_measurement:
  action_runner.MeasureMemory()

[rnephew (Reviews Here), 2016/08/25 15:28:57]

Done.

There's a lot of code duplication between this file and loading_stories.py
(_Login and _DidLoadDocument methods of the Gmail stories). I suggest you either
fix it (you'd probably need to define a new file in the system_health folder
with common code such as CloseMobileInboxInterstitial, LogIntoGmail, ...), or at
least add TODOs.

[rnephew (Reviews Here), 2016/08/25 15:28:57]

Added todo, will start working on merging them next week.
