Hi all,

I am detecting some lock contention in my application, and while reading 
up on this I came across the concept of lightweight mutexes versus 
supposedly non-lightweight mutexes. I am wondering, can Boosts 
non-recursive mutex implementation be considered lightweight? In 
boost/detail I see lightweight_mutex. Should I be using that? I need no 
interprocess support here, and I want the lock to be as fast as 
possible. If I do decide to use lightweight_mutex, is it compatible with 
the regular non-recursive Boost mutex so that I can use it with higher 
level classes like lock guard, condition variables, barriers etc?

Thanks in advance for any insight.

Kind regards,
