Comment:

 Hi,

 any patch that makes the code more efficient is welcome. Boost.Thread is
 an old library that doesn't make use of spinlocks.

 Ideally, I will prefer a patch that allows to switch to the new optimized
 version usedg a compiler flag. The reason is that we have a lot of
 platforms and we need to verify the new code before removing completely
 the old one.

 What do you mean by an initial patch?

 Ah, BTW, I've moved this to a task/optimization ticket, as it is not a
 bug/problem.
