Very valuable info for RunRev.  Thanks for taking the time to verify 
that test.

I'm wondering if it isn't script execution at all, but perhaps memory. 
I can't think of any way your script could be affected by the mere 
existence of other scripts, since your main handler is pretty well 
self-contained (so "send" or other such things which might give RR's 
scripts some chance to intercede).

I don't believe that the scripts RR's standalone maker insists on adding 
to one's project are all that large, but perhaps in an intensive 
environment such as your image processing script requires the difference 
may be just enough to affect performance.

How much RAM is installed on your machine?

I'm grasping at straws here, but this is such an unexpected result that 
as far as causes go it may be worth remaining open to possibilities 
which may even seem unlikely.
