How can I kill a 16bit process held by nvtdm.exe?

Question

I have a c# application that monitors wmi process start / terminate events. I need to also detect an old legacy 16 bit application starting. I am able to determine if my legacy app starts using code I found in this link - 16-Bit Apps running under NTVDM

But here's my question... Say I want to kill a 16bit process that was started by ntvdm.exe, how would I do that? I don't think I want to kill ntvdm.exe itself incase it is managing other 16bit process or whatever not related to my code.
