Found it...

update-master-directory-list was trying to be smart and failed.  If it
saw that a directory's ctime hadn't changed, it skipped it and moved
on.  But, a directory's ctime won't change if one of its _subdirectories' ctime_
changes.  Because u-m-d-l runs every 30 minutes or so, it appears to
catch tree updates mid-flight.  In one run it sees updates/10/x86_64/
has changed, but that repodata/ under that has not (yet).  So it
marks updates/10/x86_64 as changed and moves on.  On the next pass,
updates/10/x86_64 of course _has not changed_, but it's repodata
subdir has.  This is what it was missing...  It would skip processing
the repodata subdir.

(and yes, this would throw off the crawler too, which people have been
complaining about being added and removed from the list somewhat
randomly...)

I'm working on a fix, which will involve changing
update-master-directory-list.  But that should be the only change.
