Sorry, but this is a fairly baseless claim because there are no "Boost" 
mutexes. Boost provides nothing more than a very low-overhead (zero overhead 
if using an optimizing compiler) wrapper over Posix mutexes on Unix and 
Win32 mutexes on Windows. As such, "Boost mutexes" cannot be slower than the 
native operating system's mutexes because they *are* nothing more than the 
native operating system's mutexes!
