Boost::bind

Boost::bind library is a useful library that I usually use for my multithreaded code, even though it is not really required in any sense. Instead of writing my own function objects to be called by boost::thread, I delegate the job to boost::bind.
However, there is a caveat and I want to share it with you today.

"The arguments that bind takes are copied and held internally by the returned function object".
So,that means the copy constructors are called for your arguments. If you intentionally used reference parameters to avoid data copying during function calls, using boost::bind blindly just nullifies your efforts :(

Two solutions exist as far as I know:

1) Plain and simple, pass pointers instead. Ok, this is too C-like.
2) Force bind to hold a reference instead of calling the copy constructors and keeping copies of function arguments.boost::ref and boost::cref does that for you
