- Now libl4 has no references to utcb page or shmat etc. - Pager does not deal with special case utcb page allocation. It instead allocates a shared page from shm memory pool. - All tasks working to original standard. Next: - Add per-thread utcb allocation from the kernel - Add larger register file for standard ipc - Add long ipc (up to 1Kb)
