79b9eea6e8 VOP_FSYNC() expects to be called with the vnode locked, so lock fvp in 
nfs_rename() before calling VOP_FSYNC() and unlock fvp immediately after.

88151c4f8c Fix a bug with df on large (>1TB) nfsv3 file servers on 32 bit client 
machines where the 'long' number of blocks in struct statfs wont fit.
Instead of chosing an artificial 512 byte block size, simply scale it up
until we avoid an overflow.  NFSv3 reports the sizes in bytes, and the
blocksize is a figment of nfsclient's imagination.

4e35cc9041 It seems that 1 was not a magic value as I thought, but a coincidence. 
Instead of applying the adjustment to processes with a start time of 1,
apply it to all processes with a start time of less than 3600.

None of this would be necessary if the start times were recorded in ticks
instead of seconds and microseconds.

bf8bb3cbd9 Do a better job of calculating the RSS for swapped-out processes: 
don't include the kernel stacks of swapped-out threads in the page count,
but do include the alternate kernel stack. jhb provided some helpful
comments on this.

51f01cb3f7 When filling out a kinfo_proc structure, if we come across a process 
whose p_stats->p_start has the magic value 1, replace it with boottime.
Some users were apparently confused by the fact that ps(1) reported a
start time in early 1970 for system processes.

89c52cff2e - Reorganize osigstack() to do the copyin first, grab the proc lock once, 
do all the various sigstack dances, unlock the proc lock, and finally do

1e2ee18100 Change the locking so that the _modify function is called with topology

The only place where we want to not hold topology is when we read

long recovery time, holding topology would prevent open/close of
any disk device.
