A little googling turned up this technical explanation:

I'm unclear why the pages need to be physically contiguous, though. Is this 
a limitation in the x86 architecture?

I'm also curious if there are any good static analysis tools that can be 
run against the kernel source to compute worst-case stack depth? Surely 
someone in the gcc group has come up with such a critter?
