Sorry Eric, I saw and have kept your email aside, but wanted to finish
dealing with PR462690 before I replied.

Yes, I think adding the machine info to the attributes is the best solution,
it was certainly what I planned to try doing.

Again, sorry; not forgotten but I should have said I'd put it on my to-do
list. It was a matter of getting major features in during stage 1 so that we
could fix any bugs arising during stage 3...
Shall I leave it with you, or would you like me to go and have a bash at it?
I'm not a SPARC expert but if you pointed me at a testcase I could go use the
cfarm machines to test a patch.
cheers,
