>Description:
Often the threads of interest in ddb are those running on the CPU.

These are marked by `>' but you have to page through to find them.
>How-To-Repeat:
1. wedge the system
2. try to find what threads are on the CPU
3. get overwhelmed by ouptut
>Fix:
Add a /c modifier to `ps' to filter by those threads on the CPU.
