In mid-August I posted a followup to a person who found a problem
installing Perl on their Apollo.  I confirmed that I, too, had a
problem with the op.stat regression test failing.  I posted my log
entry:

     op.stat... FAILED on test 1
        This test opens a file and then looks to see if there is one hard
        link, but the link field is still 0.  When I added a close before
        the stat, this test worked (but, naturally, test 2 failed).

Jim Rees responded: 

   I'm not convinced.  I just tried it a bunch of ways, including
   using creat and open for read and/or write, and fstat as well as
   stat.  I can't get it to do anything unusual.

The failure happened again when I installed patches through 37.  On a
hunch I CRPed onto the node whose disk contains the Perl distribution
and the problem went away.  It appears to have something to do with
cross-node I/O.  It's nice to know I wasn't seeing things, but kind of
scary that such differences from normal UNIX behavior still exist.
