Remote Inspector changes look fine to me.

Does the __thread code patch not work in the iOS simulator? If it does work, I think it would be slightly better, so we wouldn't have the brittleness of defining this constant for ourselves.

[Mark Rowe (bdash)]

It's not necessary to check defined(__has_include) in Mac-only files.

No, __thread isn't available when building for iOS Simulator. Filed bug #135895 to consider adding logic for toolchains that don't support C++ thread local storage. I'll add a FIXME comment that references bug #135895 for now.

Will remove the check for "defined(__has_include) " from the Mac-only files in this patch before landing.
