I know all this. I did this myself :)
Debugging is currently not the main problem IMHO. Performance is.
So I am glad you are investigating threaded fastcgi, I will be one of the first to test :)
Although I am sure this will raise other problems when converting existing fastcgi processes:
such as DB access which is not thread safe,
cached data access which must be made thread safe etc. etc. etc.
