Yep.

Yep, I knew that.

Ha!  I wasn't aware of that.  Thank you!

I've confirmed on AIX 5.3 that read permissions are what counts, but it
shouldn't hurt removing the others as well.

I'd like to avoid giving more permissions if the user set, say, umask
077 before.  Thus let's just remove those for others.  I've applied the
patch below and put you in THANKS.

Cheers,
Ralf

    Fix testsuite cleanup warnings on AIX with NFS.
    
    * tests/testsuite.at [ aix ]: Set file mode creation so that
    'others' have no permissions.  Shared libraries are kept in
    memory on AIX after use if they are world-readable, which means
    on NFS mounts cleanup of test group directories will fail later.
    * THANKS: Update.
