The goal with the statfs() call was to verify that we're not on a 
persistent filesystem; I think I'd prefer it to be there.

It looks like the only changes you made were the chdir() and removing 
the statfs(), right?  From your previous post I suspect that statfs() is 
simply broken in klibc (not really surprising since I just made big 
changes to it last night.)  I'll see if I can make it cleaner.
