Comment (by rwbarton):
Regarding comment:19: this is only needed for the subsequent change to
make `coreBindsSize` less strict without introducing new space leaks. It's
not needed to get the space usage under control in the first place, for
which Phab:D3421 should be sufficient.
That said I think it is still worth pursuing that line, I'm just not sure
about the timing for 8.2.1.
