I just want to remind that boost.thread is much wider library than C++11 threading library. For example two feature that from my point of view C++11 threading library less attractive than even trivial wrap of pthrads library (or just using C API as is): - Read-Write locks - Thread local storage So going to "Standard library" directon is step backward. If you need C++11 compient interfaces this is what boost-tr1 for.   Artyom Beilis -------------- CppCMS - C++ Web Framework: CppDB - C++ SQL Connectivity: >________________________________ > From: Rob Stewart <robertstewart_at_[hidden]> >To: "boost_at_[hidden]" <boost_at_[hidden]> >Sent: Tuesday, January 1, 2013 11:05 PM >Subject: Re: [boost] Release managers: Boost.Thread breaking changes in 1.53 > >On Jan 1, 2013, at 10:12 AM, Olaf van der Spek <ml_at_[hidden]> wrote: > >> On Mon, Dec 31, 2012 at 6:08 PM, Tim Blechmann <tim_at_[hidden]> wrote: >>>> 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? >>> >>> because one might want to run on systems with an older toolchain? for one of my projects, i have to stay compatible with gcc-4.2 for older osx compilers and with mingw/gcc-4.4 ... >>> >>> being able to conditionally pull std::thread or boost::thread into scope helps me a LOT in the transition without breaking old compilers. there are a couple of other boost libraries which have the same purpose (atomic, chrono, move) >> >> Wouldn't it be simpler to use boost::thread in all cases? >> Anyway, conditionally using boost or std::thread does not require these breaking changes, does it? > >Of course it does.

For example, I make good use of  interruption points and I haven't taken the time to figure out how to do without them.
