We should call this one something like "gpu-sandbox-delay-init".

[jln (very slow on Chromium), 2014/03/20 00:21:01]

It would be nice to make it clear that the "normal", expected behavior is the
one that NVidia is now following. I would prefer if Mali was the one that
requires a special "early initialization" flag.

Since it's not a trivial change, maybe a name such as
"gpu-sandbox-start-after-initialization" or the one Jorge suggested is ok in the
meantime.

But it'd be nice to reverse the polarity and have Mali use
"--do-sandbox-early-init-with-horrible-hacks-please-dont-use-me" at some point.
