+ add birth time for systems that have it

+ fix the 64bit seek issue across Solaris and others

+ check for unsigned/signed bug in 64bit solaris

+ fix the locking issue better:
	move to a fixed length record for each inode (no spaces):
	Version Pid Time Lines Inode Device \n
		V03 P0ab17f T4353acd3 L00000555 I0001eaac D00004a00
	Add a table for the (-S) symbolic name (fixed length, full path)
		Nlseek:char[1024]

	Implement better locking:
		lock the index (wait for it)
		find the symbolic entry
		locate an inode entry from the symbolic, lock it
		under -S if the previous inode record is not the current
			symbolic result over-write the inode record
			(if not "in process")
		unlock the index
		if the inode is "in process" check the pid {
			unlock the inode record
			while wait a while {
				 break if process exited
			}
			lock the inode record
			pid still the same?  zero it
			unlock the inode record
			then goto "lock the index"
		}
		mark the inode found as "in process" (with our pid)
		keep the inode lseek, unlock the inode
		<since>
		try to re-lock the inode
		update the inode record -- if we are still the pid
		 (if the inode record is beyond the current EOF forget it)
		unlock the inode record

+ -R should take a suffix on the count (see wc's options)
	-R 4n	replay 4 lines (the default)
	-R 50c 	replay 50 characters
	-R 2b	replay 2 (512 byte) blocks

+ -R doesn't work for directories (document at least).  We could sort the
  list (of included) entries for a replay -- too much I think
  (suggest using datecut).

+ add a symbolic name tag (-N name)


Nothing below this line is sane.

~ Provide a way to remove all the entries for files that do not exist:
  that's hard as we can only see the ones we can ftw to.  I really
  don't want to ftw (file tree walk) the whole machine (NFS too?) to
  find all the files.  I think you just rm the .since file and enjoy
  some duplicate data.

  More to the point: build a .since file for each application, don't
  use the default and remove it when you know it is safe to do so.
