Comment (by starlight):

 >What is EntryNodes set to?

 Not willing to reveal my guard.  Is a single high-quality, long-running
 guard running 0.2.6.10.

 >Is StrictNodes set?

 No, but don't have ExcludeNodes set so what difference would it make?

 Issue is that for days a new high-weight exit was not selected by the
 normal routing algorithm and the new exit was refused as a choice when an
 attempt was made to force it.

 Should have traced this when it happened but it so surprised me I didn't
 think of it.  Have a script to enable debug tracing for the next time I
 see it, but I turned UseMicrodescriptors back on since its misbehavior
 bothers me less than this issue.  Can put back UseMicrodescriptors 0 and
 try to reproduce with debug tracing if desired.
