 ## Known Limitations
 
-* the Tcl event loop is not automatically invoked after `eval` or `call` returns, so any Tcl timers or events will not be triggered.  To keep the Tcl event loop alive in an asyncronous Node-compatible style, you must periodically invoke `interp.process_events()`.  See the included `example3.js` for an example of how to do this.
