panic during install

    Chris, it turns out that this 'dup alloc' issue might be a real bug
    after all.  DR is getting them on several machines.

    It is possible that the dup alloc's are being caused by memory corruption
    related to the accept() changes we just made e.g. starting on the 6th
    and 7th.

    DR and I are testing a fix right now.


:While testing the installer, I got a panic in a seemingly random place. 
:I don't have a dumpdev or a debug kernel on the installer image, so I
:can't get a dump with symbols (until I can reproduce it on the installed
:system, if I can,) but here's what I do get (minus addresses):
:during "cpdup -vvv /var /mnt/var" :
:free inode /mnt/var/60 had 7200 blocks
:free inode /mnt/var/61 had 256 blocks
:mode = 0400, inum = 62, fs = /mnt/var
:panic: ffs_valloc: dup alloc
