Awesome, thanks for tracking this down. This looks trivial to fix - we're just missing a lock statement. I've added the lock to my next change that will go in (probably today).

Hi Dino, I modified the importing code a to spit out the CLR trace and to auto refresh the browser if there is no error. 299 reloads later it crashed because it ran out of memory, looks like IE/silverlight has a leak. 108 reloads after that I hit paydirt. There error was in another module, but appears to be the same issue.
