Two points:

1. I have a TSX capable policy based compile time configurable spin
lock in AFIO which might be useful. It really ought to enter
Boost.Detail. It should work in shared memory.

2. Later today hopefully I'll ask this list for review of a new
Boost.Thread object, the permit. The underlying POSIX permit written
in C works in shared memory (the C++ object not so).
