This is great stuff, thanks!
Note that /proc/self/maps appears nowhere in phobos or druntime. So I'm
assuming that's some other function that's doing it (maybe in libc?)
The clock_getres calls are so you can use core.time.MonoTime. rt_init
initializes those so they can be used early in the process. I would
assume those are really fast, as they are constants in the kernel.
