Yeah. And the problem here is in part that we're calling chmod on a file 
linked to a file external to pseudo, but we're also checking that file's 
mode to find out what permissions we want it to have. Which is probably 
an error.

So, it does look like we need the tracking, but also if we stopped 
doing:

	stat file1 # obtain mode
	ln file1 file2
	chmod <mode> file2

we'd save significant time AND avoid the problem.
