Is it really intended that the stack size, specifically bumped to 4 pages in 
include/asm-x86/config.h for x86-64 when
debugging, gets shrunk to a single page in memguard_guard_stack()? To me it 
would seem much more reasonable if indeed
only the first page (or at most, the first two pages) was used as a guard page 
here.

Thanks, Jan
