'_v' attributes are stored on a per-database-connection basis, which is 
sort of like per-thread storage.  If you hit it several times quickly, 
you are likely to get served by a thread that has a copy of the object 
with no '_v_inqueue'.

At a quick glance, you could probably get around this by using a 
module-level registry of inqueues.
