           Summary: IndexedDB: Implement "delete pending" flag on database
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jsbell at chromium.org


The IDB spec http://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html says:

Databases has a delete pending flag which is used during deletion. When a database is requested to be deleted the flag is set to true and all attempts at opening the database are stalled until the database can be deleted.

This implies that calls open following delete should succeed, yielding a new database with the same name as the old one. Note that a delete may be delayed arbitrarily. We do queue up open calls after deletes, but it's unclear from code inspection what the open() call actually gets - pointer to the same IDBDatabaseBackendImpl object? A reset version? Is the backing store reference retained or dropped?
