I am still receiving those events and watching as my memory footprint grows until the ruby executable finally dies at around 1.5 GB.

COM has a fairly elaborate protocol for memory management 
responsibilities across interfaces. Its been quite a while since I have 
had anything to do with it, but I am pretty sure that the receiver and 
generator of COM data needs to explicitly free via the appropriate COM 
procedure.
