Whatever bit of code is starting a thread (or otherwise permanently
consuming resources) on ShellExecute is broken, not Emacs. I don't think
I've seen that behavior myself. What's the thread start function on that
new thread? What's on its stack?
Anyway, you should be able to work around the problem by using cmd.exe's
"start" builtin, which will run ShellExecute on your behalf.
