Is set safe to use? If Uint8Array prototype is modified, we probably cannot use set directly.
We could probably do something like @Uint8Array.prototype.@set.@call(...)

Can you verify UInt8Array.set and fix it if necessary

I checked @Uint8Array.prototype.@set.@call(...) but it doesn't work, @set cannot be resolved. I tried to fix it in different ways but couldn't, initialization of @Uint8Array and public/private methods wasn't clear to me.

As discussed with you, I will land the patch with a FIXME and file a corresponding bug.
