Just when I thought everything was working....  Earlier today I saw an
MCHK trap in uvm_analloc.  Now I've seen a new trap:

panic+0x19c
trap+0xfc
kernel MCHK trap by splraise+0x20: srr1=0x49030
    r1=0xd5433c80 cr=0x88004042 xer=0 ctr=0x29d2bc

ufs_rename+0x524
VOP_RENAME+0x50
rename_files+0x2c4
syscall_plain+0xe0
user SC trap #128 by 0xeff0775c: srr1=0xf032
   r1=0xffffda70 cr=0x44004084 xer=0 ctr=0xeff07754
saved LR(0xfffffffb) is invalid

I was extracting man.tgz with pax in single-user mode when this panic
occurred.  This is with 1 day-old -current; I'm going to update to this
minute's sources and try again.
