Is node->renderer() always non-null?

Is everything in this chain always non-null?

Not sure you need this (see later comment).

Can't you just call startOneShot() and avoid touching Timer.h? I don't think you even need to call stop() beforehand.

I believe so. The renderer is already accessed earlier in subframeLoaderWillCreatePlugIn(), which is the caller of this function.

I cannot guarantee it is. I will add checks for mainFrame() and view(). page() is already checked earlier in this function.

Yes, you're right. Amended.
