ControlPlane stops switching contexts or uses excessive CPU

I’m hearing reports that recent versions of ControlPlane fails to change contexts after it has been running for awhile or will use excessive CPU time.  I’m looking into the issue but it would be helpful to hear from anyone who is having this issue.  If you are having either of these issues please report it at http://github.com/dustinrue/ControlPlane/issues and provide information about what evidence sources you are using.
