Subject Re: incorrect pass rate for 23.deque.iterators on Windows
Date Tue, 27 Mar 2007 14:57:00 GMT
Greetings Martin.

I have noted this incident on my todo list, and I hope to have a chance 
to look at it next week.  I am somewhat occupied with other projects 
this week, and this would have a lower priority.
