[Boost-users] [signals] thread_safe_signals feature-complete

Hi all,

I've finished thread_safe_signals.  To get thread safety you have to 
include an additional header file thread_safe_signals/multi_threaded.hpp 
and set the last template parameter to boost::signals::multi_threaded.

I've done a little benchmarking.  With thread-safety off and connecting 10 
slots, it appears to have about the same overhead as cvs boost.signals 
(which is much less than the latest release of boost.signals).  When 1 
slot is connected, it has more overhead, a little less than a factor of 2 
when running a single empty slot.  Turning thread-safety on increases 
overhead by about 50% for the 1 slot case and 100% for the 10 slot case.  
It is able to invoke slots concurrently though, which should be a win if 
the slot is non-trivial.
