Unfortunately no luck.

The IIS Admin Service (inetinfo) is running under Local System and W3SVC
(iissvcs under svchost.exe) runs under Local System also. The ASP.NET
process (w3wp.exe) is run under Network Service (but I've tried Local System
also). Thus setting the envvars in SYSTEM should get them to all these
processes.

Here are the various techniques I used to try to "restart"

1. Used iisreset /restart
2. Used Services control to stop IIS Admin, W3SVC and HTTP SSL.
3. Used IIS Manager to stop the Default Application Pool and the Default Web
Site, and then started them again.

I am most surprised that iisreset didn't do the trick.

For grins, I rebooted the box with enable=1 and got the tracing running.
Then I set it to 0 and tried to see if I could get it to shut off (just in
case there was something funny with the tracing), but I couldn't get that to
work either. Definately the envvar not getting propogated into the right
process.
