FWIW, Asio's io_service also suffers from the computational cost of thread_specific_ptr. Would be great if those costs could be reduced.
I was concerned with thread_specific_ptr performance, too. Although this was in pre-1.41 times, I still think there's room for improvement. I crafted a patch for 1.40 that provided constant-time complexity of reading/writing to TLS instead of logarithmic that is present now in 1.41. It has its downsides but if anyone finds it interesting, it's attached to this ticket: https://svn.boost.org/trac/boost/ticket/2361
