I assume if I were to look at this bug that it would explain why it is beneficial to add this logging.

Not at my computer. I am assuming we fixed the referenced radar and hence we can enable this. The ChangeLog didn’t mention this fact and EWS failed to compile this patch for iOS due to another issue below.

According to the EWS we don’t have a logging channel called Threading.

Correct.  Added more detail just now as well.

Yes, it's fixed.  I'll add a comment to the ChangeLog.

Weird.  I thought it was defined here:  Source/WebCore/platform/Logging.h

Maybe I forgot to #include that.

Added missing #import "Logging.h" to WebCoreThread.mm to fix the iOS build failures.

Also updated Source/WTF/ChangeLog with info about the fixed radar.
