I think it's best to bump libc and also provide compat functions
for the syscalls that have changed. struct ipc_perm also needs to
be updated (ours is still using unsigned shorts for things like the
uid).
I'll help finish things up at the sys_/kern_ separation stage if Jan
gets overwhelmed with the extra work. I really want new kernels to
be compatible w/ release kernels. I don't want to break compatibility
right off the bat.
