There are a few known problems:

        * We're running Mar 9 software on the testbed.  Since Mar 9,
          some bugs have been fixed.  I do not remember which ones.

        * There is at least one bug in the Mar 9 SPF code.  One SPF bug
          triggers a diagnostic assertion and core dump---hslsd prefers
          to commit seppuku than to live with the dishonor of a fubar'd
          routing table.  I believe I fixed that bug last night (I have
          not checked in the fix).  Of course, the Mar 9 software does
          not contain that fix.

        * There is something wrong with ETX so that it produces metrics
          less than 256 (the nominal minimum).  I am not certain that
          this adversely affects the testbed operation, but it might.
          I have a pretty good lead on the cause of this bug.

I know of a new bug on the trunk: on our indoor testbed, it looks like
ETX dumped core on two nodes as it tried to interpret a scrambled buffer.
I'm going to leave some hslsd running overnight to see if it happens
again.
