Resident memory usage from the "StartSettled" data for fx-team push changesets:

e7f97fa8a86b : 149073920
a1639dd9dd3d : 150249472

e6636696d6de : 149680128
7c458c70cd5c : 158826496 <-- regression!

b07f0ec10d22 : 159027200 has 4 patches by Margaret, not sure which one caused it yet. The regression appears on the "explicit" data as well so this isn't just Android randomly loading in more stuff into resident memory.
From a quick look at the about:memory dumps there's a whole bunch of devtools stuff that wasn't there before, so this is probably bug 979101.

jryans, have you ever noticed memory problems like this with B2G? I imagine the remote debugger is also disabled by default there, so maybe this hasn't been an issue.

I should probably just back out bug 979101, but that makes me sad.

Yep, it's been a B2G issue too.  In fact, worse there to some degree, as there's not enough memory to run the Dev Tools at all on low end B2G devices.  :(

I am not sure there are any quick fixes here, so yes, you may have to back it out.

Fixed by the backout in bug 979101.
