autoclosing windows

I've asked on irc and gotten some partial resolution.  But I will be
too busy to spend a lot of time on irc for the next couple of days so
I'll ask here.  Also, email seems to allow for a more complete problem
statement than trying to stuff things in one 79 character line at a
time.

I want unused windows to automatically close.  I found
'autoclose_query' and 'autoclose_windows', which I have set to 300 and
ON, respectively.

I'm using Bitlbee for Twitter, Facebook, AIM and GTalk.  I have things
set so that each person or account I msg/query has a separate window,
auto created if necessary.  For the Twitter account, this means
'account twitter set mode many'.

As far as I'm able to figure, the 'autoclose_query' is working fine.
Each query window displays 'Irssi: Closing query with someuser' after
the 5 minute time limit.  But the window is not closed.  This appears
to happen with every query, regardless of the protocol being used.  I
have tried setting 'reused_unused_windows' to ON and OFF.  If this
setting is on, query windows used again as expected.  I don't know if
those two settings conflict with each other or not.

I was asked in channel what the output of '/win' was.  Before the
query was closed:

2011-12-15 12:33:03 |CLIENTCRAP| Window  : #109
2011-12-15 12:33:03 |CLIENTCRAP| Size    : 279x71

   Server tag
2011-12-15 12:33:03 |CLIENTCRAP|  QUERY  : gnat
   Bitlbee

After the query timeout, the output is:

2011-12-15 12:39:06 |CLIENTNOTICES| -!- Irssi: Closing query with gnat
2011-12-15 12:40:15 |CLIENTCRAP| Window  : #109

Any pointers on how to make this work?  Do I need to write a script to
cycle through the windows and close any that have closed a query?
