Created attachment 270141 [details] Patch

This patch does not apply because it depends on the patch for bug #153157, which changed the parameters taken by DedicatedWorkerThread::create(). I will rebase this patch before landing if this patch is reviewed before the patch for bug #153157.

It seems somewhat strange to have a one-off variadic template here, since the number of parameters will never actually vary in practice. I wonder if we should consider creating something similar to std::make_unique for Ref and RefPtr? That would let us remove this type of duplication all over our codebase.

I proposed this change because I've modified DedicatedWorkerThread::create() once in the patch for bug #153157 and plan to modify it again in a subsequent patch. Maybe we can come up with a better design for passing state to Web Worker threads. Currently, whenever we want to pass state to a Web Worker thread that cannot be derived from the existing state we passed then we need to modify DedicatedWorkerThread::create() among many other functions. > I wonder if we should consider creating something similar to > std::make_unique for Ref and RefPtr?

We should try this!

Yeah, that'd be nice, since it'd let us keep the constructors private.
