Yup, we can drop this part. Originally, I was considering about
in WebKit2 thread => "Apple WebKit: xxx".
But I think just using "WebKit: " is OK.

If we recognize the [UpperCharacter]*[LowerCharacter]* as word, we can
split it as "GC Controller".
But anyway, it causes a problem when we encounter a name like

I think we should not truncate the name for Linux.
My automatic shortening is based on the fact that "org.webkit.MODULE.NAME"'s
NAME part is always <= 15 characters. So we do not truncate.
But if we have names like "Asynchronous Indexed Database Server" and
"Asynchronous Indexed Database Client", the both become "AsynchronousIndex"
It is not helpful.
However always using 15 characters names effectively limits the ability of
macOS's thread names.
So now, I like Geoff's idea, having 2 names, long name and short name.
For example, we have "Asynchronous Disassembler" and "AsyncDisasm".
Then, in macOS, use "WebKit: Asynchronous Disassembler".
In Windows, use "WebKit: AsyncDisasm".
In Linux, use "AsyncDisasm".

Yeah, we can add JSC prefix in long name part if we want.
