I think I'm seeing a panic tickled by AFS.  I can't tell for sure, for a
variety of reasons, but I believe I'm getting the panic:

pmap_enter: malloc returned NULL

Now, this occurs inside arch/i386/i386/pmap.c in pmap_enter() if
malloc(M_NOWAIT) for a pv_entry_t fails to find any memory.

I suspect this is just somebody stealing all the kernel memory, and
leaking it somewhere, but I figured I'd ask if anybody here has seen it
before and knows of some other diagnosis?
