Presumably this is the "special purpose allocator" mentioned on this 
page or something like it:

   http://www.boost.org/doc/libs/1_36_0/libs/smart_ptr/smarttests.htm

However, I don't find any mention of BOOST_SP_USE_QUICK_ALLOCATOR in 
the documentation.  Have I missed something?

Is there a reason for not making BOOST_SP_USE_QUICK_ALLOCATOR the default?
