crrev.com/c/783707 landed a call to GetCollectStatsConsent()
that seems to end up in a disallowed blocking call, and
it's preventing my simplechrome on soraka from booting up,
the crash stack says:

[27334:27334:1127/100516.056462:FATAL:thread_restrictions.cc(29)] Check failed: !g_blocking_disallowed.Get().Get(). Function marked as blocking was called from a scope that disallows blocking! If this task is running inside the TaskScheduler, it needs to have MayBlock() in its TaskTraits. Otherwise, consider making this blocking work asynchronous or, as a last resort, you may use ScopedAllowBlocking in a narrow scope.
