> Suppose the impl thread deletes all textures via releaseContentsTextures().  The impl thread will not be able to draw again until resetContentsTexturesPurged() is called in scheduledActionCommit().  When deleting the textures, the function releaseContentsTextures() calls setNeedsCommitOnImplThread() to ensure that a commit will come along to allow drawing again.  If this commit is aborted, then the page will not draw until a commit is scheduled, which may be forever.

What about setting needs-commit when the compositor becomes visible? beginFrameAbort only happens when not visible.
