Funny thing, windbg apparently uses a fixed-size buffer to store the old-style thread names and it must use strncpy to copy them in because if your thread names are long enough then windbg displays the first ~15 characters and then shows garbage, because strncpy doesn't guarantee null-termination.
Harmless I think, but sloppy.
That limit makes it pretty hard to provide meaningful identifiers in a non-trivial application.
