Is there any way I can monitor the progress of a given tree through the
whole 0-day testing farm? I know the various compile tests are complete
because those send email. But after that it goes off into magic land
without further feedback, unless something bad happens as per this
report.

It would be useful for me to know how far along a given tree is before I
zap it.
