 The -current install kernel does not panic on boot, but it is still 
 unstable.
 
 Running the same test as described in the initial pr on an installed 
 -current yields a panic, with the following backtrace (hand copied):
 
 ffs_copyonwrite+0x9c
 fscow_run+0xaf
 ffs_alloccg+0xd9
 ffs_hashalloc+0x2c
 ffs_alloc+0x128
 ffs_balloc_ufs1+0xcc4
 ffs_balloc+0x69
 expunge+0x322
 ffs_snapshot+0x1091
 VFS_SNAPSHOT+0x2f
 ffs_ioctl+0x73a
 VOP_IOCTL+0x6a
 vn_ioctl+0x62
 sys_ioctl+0x11e
 syscall+0xab
 
 
 So while there have been changes, it looks like FFS snapshots still 
 aren't playing nice when stressed.
