Anyone have flyspell + autocorrect working?

[Tory S. Anderson]

I find that trying to have both flyspell and autocorrect-ispell working in the 
same buffer results in unusably slow autocorrect behavior; if I start a word, 
it takes up to 5 second for a suggestion to appear. I am using the hunspell 
dictionary for both. Upon disabling flyspell, ac-ispell works fine. Anyone have 
these two working in tandem? How did you do it?
