No. I mean comparing the pointers.
Of course I know, that there is no boost equivalent of pthread_self 
available out
of the box.
However you can easily work around this even without modifying 
boost::thread if
you need it.
During startup of the thread you would manage to store a copy of the 
pointer within
a tss variable. If you want to know how this works I can post you an 
example.

This pointer, say "this_thread" can then be used exactly like 
pthread_self can be used
(with equivalent sematics).

Of course your last statement is also true. But since boost::thread is 
not copyable (which is a good thing)
it cannot be used easily to identify a thread.
