This is used in order to give plugins a handle to the native widget. It seems easy to pass this handle down to the TabChild at creation time, but we should probably do that after bug 1343728 lands. That way, it should be super simple to remove this sync IPC.
Jim, can you confirm that once we're windowless-only we don't need this handle any more?
(In reply to Benjamin Smedberg [:bsmedberg] from comment #1) > Jim, can you confirm that once we're windowless-only we don't need this > handle any more? I don't think we can remove windowed support as long as users have the ability to disable Flash async drawing. Also, we probably have a large population of facebook game users who have this off, remember Zynga was advertising to users to disable it for a while on at least one popular facebook game. We could change the pref name maybe, but I don't think we should remove the ability to flip a pref to test the old windowed mode until we're sure async drawing is going to stick and work for everyone. I'm open to being convinced otherwise though, I'd love to rip out a ton of windowed mode plugin code.

I do want to aggressively rip out the windowed-mode support, but probably have async drawing on release for a release cycle first. But in this case the question is specifically around prioritizing QF work. If we only need/send this message with windowed-mode plugins, then this is "fixed" with async drawing.
Asking billm for review on the changes to sync-messages. bz - I am not sure who should review this change - but I saw you had reviewed some code which touched this code, so I'm asking you. MozReview-Commit-ID: Bql29wgVDZ5
This patch doesn't depend on bug 1343728, although I have written it on top of the same tree, so I'm removing the dependency.
