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.

Q: Could a bounds fault be handed to userspace and the tables allocated - there in a signal handler intead of in the kernel? + 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. |
