This does not work for cgminer. At least for the cgminer I have used.

Don't use cgminer. Use pooler's cpuminer aka minerd.

There are probably more up to date releases but without knowing your OS I don't want to go searching.
In miners you can use the -t call to specify the number of threads. So if you have 4 cores you could do "-t 3" and have only 3 threads. This does not leave an entire core open but it should have all four cores at ~75% usage. At least that is my experience.

I don't believe there is an option to specify number of course (but I could be mistaken)
However, putting cgminer on low CPU priority works well for me (assuming you are using Windows):
1. Start cgminer
2. Open Windows Task Manager
3. Switch to the "Processes" tab
4. Find the cgminer.exe process related to your CPU mining
5. Right-click this process, choose Set Priority -> Low
This will allow this instance of cgminer to use 100% of CPU resources, but allows other tasks to "steal" CPU time if needed

When CPU mining alternative coins, what flag do I need to pass to cgminer to use all but one core? I want to avoid using all cores because it would affect my GPU scrypt hash rate. (I'd like to use the CPU to mine a CPU-friendly coin, which is different from what I mine with the GPUs.)
