Undefined action in stylesheet cache

I keep running into an intermittent issue with the stylesheet cache that seems to originate from kontroller/lib/flow-control.js. From time to time the browser losses its stylesheets completely and outputs an error similar to:
Error: undefined action stylesheet=#cache_c0cad.....

that seems to originate at flow-control line ~67. Which is called from compound/lib/controller-bridge.js line ~169.

restarting the node process always fixes the issue, but continues to occur on rare occasions.

The issue points to kontroller/lib/flow-control.js around line 67 and compound/lib/controller-bridge.js around line 169. Start by examining the stylesheet caching mechanism in those files. Reproduce the intermittent error by monitoring stylesheet cache actions. Look for undefined variables or race conditions in cache handling. 'Done' means identifying the root cause and proposing a fix.
