In C, global data is compiled as part of the executable image, right?
So what happens when the Memory Manager decides it's time to clean house?

		Some guesses:
	1) Code segments aren't simply purged, they're saved back to disk
	2) Global data is clobbered when the segment in which it was declared
	    is unloaded.
	3) Mac compilers are smart enough to keep all global data in seperate
	    resources which cannot be purged.

My money is on #3, does anyone know for sure?

Thanks, email is sufficient.
