Given the scope of the changes you describe -- you wrote "'s
patch is so big they may as well have re-released the whole program."
-- I can't get upset at taking a month to fix it.  You're dealing with
asynchronous events, which are really hard to start with.  I suspect
that they spent some time deciding how to fix it -- you don't appear
thrilled with their choice, but I don't know what other options they
considered -- and then actually tested the new code.  Given how many of
our security problems are due to buggy and inadequately-tested code, I
suspect that taking a month was actually being quite responsible.
