I looked all over the various thread related messages, and while there are a bunch of opportunities for this to be handled, it isn’t really there.

Similarly, there is qThreadExtraInfo which allows for a free form string.  And there is qXfer:threads, but that carries only an ID and a core number.  And none of these seem to be cleanly tied to the main gdb thread name machinery.
