...

mark pages whose refcount were >1 and drop to 1 and are
...
read/write writable in the pagetable right away instead of waiting for
a pagefault. minor optimization.
some a sanity check of SLAB-allocated pointers.
vm gets its own _exit and __exit like PM, so the stock (library) panic works.

Basic VM and other minor improvements.
