I'm well aware that getcwd() is not a syscall. Please look at what I
wrote. The fact that memcpy(3) is implemented in user space does not
imply that similar functionality is not availible to kernel code,
perhaps with different name and arguments (eg, bcopy()).

*Huh?* I have absolutely no idea what this means. What does this have to
do with the size of corefiles?
