Hi Vicente,

what do you think about having a monotonic allocator using a thread specific

This seems like a good idea. How about:

std::list<int, monotonic::allocator<int> > global;
std::list<int, monotonic::shared_allocator<int> > shared_global; // uses
mutex
std::list<int, monotonic::local_allocator<int> > thread_specific_global; //
doesnt use mutex

This is now in the sanbox at
https://svn.boost.org/svn/boost/sandbox/monotonic/boost/monotonic/local_allocator.hpp,
but untested. I am yet to write a test harness for multi-threaded
applications.

Thanks for the idea Vicente,
