--- Comment #9 from Brady Eidson <beidson at apple.com> ---
The plot thickens...

The MemoryObjectStore keeps both a HashMap of keys-to-values, and a std::map of ordered keys.

Every time we insert a record, we record the key-value-mapping in the HashMap, and insert the key into the std::map for ordered-ness.

The bug is happening because the HashMap *thinks* it has a record for this particular IDBKey. But the std::map does *NOT* have a record for the key.

Lots of printf-style debugging confirms that we've never tried to put this key in either the HashMap or std::map before, nor have we tried to put anything with its hash in those maps before...

Did this test discover a bug in our HashMap?
