Svchost: How to make it run only one module per instance of svchost.exe? How to get extended process info?

Question

I have an issue with one of my applications. I run the application, everything is okay. When I close this application, I notice that one of the "svchost" processes in the system takes up about 95-100% of the CPU and I have to figure out what is taking up so much of the CPU cycles.

I set myself pretty simple and straightforward goals on how to go about this:

1. Get the process info or this particular "svchost" that is taking up so much CPU
2. I know what an svchost process is used for, so I save you guys the effort to explain me about it. So now I must know which modules are loaded by this rogue svchost.
3. I ran my application, closed it and made sure that my process is completely closed, not anymore in memory. I then got the PID of the svchost taking up 100% CPU
4. I ran ProcessExplorer (from sysinternals), got the info about how many and which services this svchost has hosted. They are about 12 services. I would not bother about this list as I am more concerned about How to IDENTIFY which one of these 12 services is taking up the CPU cycles.
5. Now I have the list with me and here starts the tricky part... I want to do 1 of the 2 options below

Option 1: How do I identify which one of these 12 services is taking up so much CPU? Can I get extended info for this svchost process that gives me detailed info on a "per service" basis hosted in this process, rahter on the process basis that I have now?

Option 2: Is it possible to configure windows to make svchost to run only one service per instance of svchost?

If there is a better option on how to investigate, narrow down the root cause of this issue, please do let me know.
