[gentoo-dev] chromium-59.0.3053.3 will require >=sys-apps/sandbox-2.11 (currently hard masked)

The latest dev channel release of chromium (59.0.3053.3) will require
>=sys-apps/sandbox-2.11 to build.

I'm sending this announcement because this version of sandbox is
currently hard masked. So is the chromium version, but with its fast
release cycle we can expect it hitting ~arch in few weeks, and stable in
the next few weeks. I'd like to make sure we'd be able to push sandbox
to stable at the same pace, or find some alternative solution.

For curious folks, new sandbox fixes a hang which occurs with tcmalloc.
See https://crbug.com/586444 . The new chromium adds a code generator
needed for build (inside the network stack). I didn't find an easy way
to disable tcmalloc just for that code generator, and after finding
above bug new sandbox seemed like the best choice.

for the commit which introduced this, and feel free to share your
suggestions.
