If we were to preallocate them for the 128TB of user virtual address
space, we would need to reserve 512TB+2GB, which is larger than the
entire virtual address space today. This means they can not be reserved
ahead of time. Also, a single process's pre-popualated bounds directory
ahead of time. Also, a single process's pre-populated bounds directory
consumes 2GB of virtual *AND* physical memory. IOW, it's completely
infeasible to prepopulate bounds directories.

Q: Could a bounds fault be handed to userspace and the tables allocated

there in a signal handler instead of in the kernel?
A: mmap() is not on the list of safe async handler functions and even
if mmap() would work it still requires locking or nasty tricks to
keep track of the allocation state there.
