The short answer is that I don't think YOU can make it thread safe - this is something 
IBM would have to do - UNLESS you wrote a wrapper that forced single threading (which 
sort of defeats the purpose)

Would something like RedBack provide an adequate alternate solution for you? (Could 
also use 2/3 of our Visage stack to work with ASP if you REALLY wanted to, but you 
then loose "nice" things like dictionary aware drag & drop designer)
