Vinay - that's great news!  Are you going to create a new bug for this issue with a proper title?  It would seem to me that the fix for this would be to put locks internal to the os.system() call around where it spawns cmd so multiple spawns don't occur simultaneously.

Is the proper procedure at this point to open a new bug with a more correct title that points back to this bug for reference?  Can you do that Vinay?  I don't know if I have the authority (nor experience with the bug tracking system) to do that.  Thanks.
