I'm not sure that it is, though.  You have a program that uses 
boost::thread.  Its still not a program that uses std::thread.

Changing boost::thread to work like std::thread causes problems for 
people using boost::thread now, and will only be a real help to 
portability if boost::thread is limited to what std::thread does.

It seems to me likely that by the time the mess is sorted out,
it is likely that compilers will offer enough compatibility with 
std::thread as defined that its a big waste of effort, and in the mean 
time everyone who has boost-based systems now has a world of pain as 
they work out when/how to 'big bang' entire systems (or at least the 
linked-together parts) over to the new behaviour.

Why would anyone writing new software on a modern platform use 
boost::thread rather than std::thread unless then actually wanted the 
old semantics, anyway?
