It was fixed on the trunk for Boost.Function long ago. It's interesting 
that the thread library no longer depends on 'function' (at least, for 
launching threads); I see how the change was done (using virtual 
functions, which was once the implementation trick used in Function), 
but I'm curious as to why? Function has some storage optimizations that 
will tend to make it more efficient that the basic virtual 
function/templated derived class idiom.
