This is a 2+ year old thread, but I believe my response back then was to use asyncSubmit instead of syncSubmit.
It may be a bug if abortAllSubmissions() doesn't wake up a pending syncSubmit(), but I do not own this project anymore, Brian W does, he is also on this mailing list so he may be able to provide more info.
