I know pdf2swf is a command line application, but it is still under the control 
of the environment
within under which it's running - or should be.  It doesn't dp the context 
switching, the o/s should.

It's not an issue - though there has been a lot of debate as to the benefits of 
enabling it on Intel

architecture Chris, not operating
system.
