Richard and I have been looking at this offlist. I've written Dave 
privately, but just to update everyone here, this is what we found:

1. There is a problem with PNGs for some reason. The export command 
fails after a certain number of itertations. In Dave's stack, this is 
#289. If you change the export type to GIF or JPEG (or maybe some of the 
others we didn't try) then there is no error after any number of iterations.

2. The memory leak is significant, but it only occurs in the IDE. It 
isn't an engine problem.  When running the same script in the MC IDE or 
as a standalone, there is no memory leak.

Therefore, Dave can probably work around the issue by changing his 
export format to something other than PNG, and limiting his tests in the 
IDE to fewer repetitions. When run as a standalone, it should be fully 
functional without any leaks for any number of iterations.

I have submitted a bug report for Dave about this, and will update it 
with this info. The bug number is #4558. Gotta thank Richard for some 
heavy-duty sleuthing on this one.
