IGeoProcessorEvents3 progress messages from python script tool?

Question

No matter what I've tried, I cannot get progress messages from a python script tool to fire any of the IGeoProcessorEvents3 "onProgress" handlers.  Is that even possible I wonder?  The progress bar does show up if I run the tool in the foreground from ArcCatalog, which proves the python tool is issuing progress notifications.  But progress events don't fire when I run the toolbox tool via Geoprocessor.execute(tool, parms).  Other handlers fire - preToolExecute, onProcessMessages, and postToolExecute - but nothing for onProgressMessage or onProgressPercentage.  Any ideas?  (ArcGIS 10.0)
