Tested on WindowsXP with a 400 K file (Rev 2.6 and Metacard 2.6.5) with 
zero delay in both cases, so it seems to be a Mac-only effect.
I tested with both IDEs as a number of processes run considerably slower 
in Rev, e.g. for some imagedata functions I get a consistent slower 
performance of about 33% inside Rev (including version 2.7.1).
