More importantly, how was the debug environment on your
processor built?  In other words, the device has something
in FLASH/ROM - this may be RedBoot or simply GDB stubs.
This is what has to be built with the thread support present
since when Insight (or GDB) is talking to the target, it's
talking to the GDB support (in RedBoot or stubs) and not
directly to your application.
