It's very ugly, but at least it doesn't seem to limit you to 15 characters like on Linux (prctl/pthread_set_name_np).

That limit makes it pretty hard to provide meaningful identifiers in a non-trivial application.

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.
