Truthfully, I don't know.  I only raise the possibility because the User 
Manual indicates there is an internal flag set by the watchdog so that if 
it is the source of the interrupt the ISP pin is ignored.  If that flag is 
not cleared somehow then any subsequent reset could also ignore the 
pin.  Off hand I wouldn't expect the length of the reset pulse to make any 
difference on whether it entered ISP mode or not.

If you have an extra pin I'd set it on startup to indicate the startup 
source.  I seem to remember you can tell that on startup, I hope I'm not 
confusing the LPC with a different processor.
