- KIP's pointer to UTCB seems to work with existing l4lib ipc functions. - Works up to clone() - In clone we mmap() the same UTCB on each new thread - excessive. - Generally during page fault handling, cloned threads may fault on the same page multiple times even though a single handling would be enough for all of them. Need to detect and handle this.
