tested it at TOT, since I don't have an Android test setup running TOT. While
I'm getting my tests ported over, I would like some feedback on adding another
tunable as well as what the tunable's interface should be--I really don't like
the 0-10

Looked at this some more, and th
I've looked into this a fair bit on the Android side, so I can provide
some context. There are two main reasons why Android gathers PSS
information:
1. Android devices can show the user the amount of memory used per
application via the settings app. This is a less important use case.
2. We log PSS
