The problem turned out to be a class variable that contained a time filter
with the "current" time.

But since it was a class variable, it was only evaluated once upon import
and its idea of "now" was forever frozen at that moment, so it always
compared as being less than any of the lock records that were passed in.

I changed it to be a class method that constructs and returns a new time
filter whenever it is called.

Thanks for everyone's help!
