I tried BOOST_SP_USE_PTHREADS and BOOST_SP_USE_SPINLOCK of which neither 
one works.
I am not willing to pay the price for losing thread safety, which is why 
I haven't tried the other define.

I know, we upgraded to the 4.4 version once and had nothing but problems
which is why we reverted to 4.2.

Thanks for your hints thus far,
do you have any idea of why BOOST_SP_USE_PTHREADS doesn't work?
I've seen that where we're using boost 1.38 it is being compiled with 
that define set in user.hpp
but for 1.41 it is not...
