I've taken the liberty to convert the patch into detail/quick_allocator.hpp. #define BOOST_SP_USE_QUICK_ALLOCATOR to make shared_ptr use it. shared_ptr_alloc_test.cpp has been updated, too. You can now compare quick_allocator vs SGI std::allocator yourself. :-) quick_allocator doesn't compile on VC6 or Borland 5.5.1, though. I haven't investigated too deeply. > My patch doesn't pretend to work for a threaded implementation, so > only the no-threads test applies. I added a lightweight_mutex lock here and there, but haven't made any extensive multithreaded tests. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
