Attachment: Patch, v1

I forgot about ctypes callbacks (which call back into JS from C). The attached patch should do the trick.

Patch, v1.1

[Approval Request Comment]
Bug caused by (feature/regressing bug #): 813867
User impact if declined: Some extensions cause crashes when using ctypes in workers. We could back 813867 out of beta I guess.
Testing completed (on m-c, etc.): m-c, m-i
Risk to taking this patch (and alternatives if risky): As with bug 813867 it's possible we could see deadlocks, though we haven't seen any so far.
String or UUID changes made by this patch: None

Patch, v1.1

For beta, I think a backout makes more sense (unless we're relying on this desktop data, in which case please re-nominate for uplift).

Attachment: Patch for b2g18

[Approval Request Comment]
Bug caused by (feature/regressing bug #): Bug 813867
User impact if declined: See bug 813867 comment 53.
Testing completed: m-c now for a while, also m-a.
Risk to taking this patch (and alternatives if risky): Now that this has baked on two other branches for a while we know it's pretty safe.
String or UUID changes made by this patch: None

[Lukas Blakk [:lsblakk] use ?needinfo]

Given that this is non-blocking we'll hold off on approving for branch landing until after v1.0.0 -- see https://wiki.mozilla.org/Release_Management/B2G_Landing which explains further but the options are either to land to the date branch now so that it gets merged into 1.0.1 after 1/25 or to wait and get b2g18 approval after 1/25 for direct landing to that branch.

I backed this out of b2g18 because it caused a perma-orange on linux pgo (only)... https://hg.mozilla.org/releases/mozilla-b2g18/rev/2035414073b7
