itty bitty IRIX questions

[Randy Carpenter]

I have a few miscellaneous IRIX questions:

  1.) Where can we get the SGI diagnostic programs that are supposed
      to be in /usr/diags?  By default, there's nothing in the 
      directory.

  2.) Why does ps(1) take so long every once in a while but then
      has good response at other times.

  3.) Why doesn't ex(1) and vi(1) look at the TMPDIR environment
      variable like ed(1) to allocate buffers?  The default root
      partition on SGI systems doesn't leave enough space in /tmp
      to edit huge files.  I don't want to have to worry about
      every user having to "set directory=/usr/tmp" in their .exrc
      files and I don't want to expand the root partition.
