So then it's apparently not required that Process Explorer be running to 
trigger this process.

Well that's easy then. Stop playing games! :-)

Seriously though, maybe Enemy Territory is interrogating the process 
table in a similar manner as Process Explorer is.

    csrss.exe is the main executable for the Microsoft Client/Server
    Runtime Server Subsystem. This process manages most graphical
    commands in Windows. This program is important for the stable and
    secure running of your computer and should not be terminated.

That's what Process Explorer is for! It can kill things that the Task 
Manager won't let you. Unfortunately killing some things, like this, is 
very determental to your system (i.e. you reboot! IIRC).
