Comment:

 Next follows the text that will be added


 {{{
 [heading Rational about the nature of the key]

 Boost.Thread uses the address of the `thread_specific_ptr` instance as key
 of the thread specific pointers. This avoids to create/destroy a key which
 will need a lock to protect from race conditions. This has a little
 performance liability, as the access must be done using an associative
 container.
