In general I'd agree that seki should be handled by owl.  However, it
would seem to me that this could result in cases where the tactics code
thinks the string is dead, but cannot find an attack point.  That seems
like a mild problem to me, and simple seki handling (treat it as tactical
life) seems like a reasonable solution.  Is there a reason this is a bad
approach, beyond it really being the responsibility of the owl code and
possible performance issues?  (Which is not to say I think those are bad
reasons, I'm just curious.)
