Apparently not.  If I start an X session (using the standard menu item
under the start menu) and manually shut it down, the lock file is not

Yes, startxwin.exe "just worked", and the replacement doesn't.

What do you mean "directly"?  From a mintty or such?

No they're not, unless you restrict "kill" to mean "kill -9" or
