launching threads
boost::thread類代表一個(gè)可執(zhí)行的線程(thread of execution)。
A new thread is launched by passing an object of a callable type that can be invoked with no parameters to the constructor.
The object is then copied into internal storage, and invoked on the newly-created thread of execution.
If you wish to construct an instance of boost::thread with a function or callable object that requires arguments to be supplied, this can be done using boost::bind.
（thread non-copiable, but movable; object that used to created a thread must callable, if not, use boost::ref）

Joining and detaching
當(dāng)代表一個(gè)可執(zhí)行的線程(thread of execution)的boost::thread對象被銷毀時(shí)，這個(gè)線程便同時(shí)被detached. Detached的線程將繼續(xù)運(yùn)行直到線程終止。
也可以顯式調(diào)用(explicitly)一個(gè)boost::thread對象的detach()方法，這時(shí)這個(gè)線程直接被detach，而這個(gè)boost::thread對象講不再代表thread of execution，而指Not-a-Thread

join()用于等待一個(gè)線程結(jié)束。
(timed_join())

Interruption
調(diào)用boost::thread對象的interrupt()方法，可以中斷其對應(yīng)的線程。
When the interrupted thread next executes one of the specified interruption points (or if it is currently blocked whilst executing one) with interruption enabled, then a boost::thread_interrupted exception will be thrown in the interrupted thread. If not caught, this will cause the execution of the interrupted thread to terminate. As with any other exception, the stack will be unwound, and destructors for objects of automatic storage duration will be executed.
(boost::this_thread::disable_interruption, Predefined Interruption Points)

Thread IDs
每一個(gè)運(yùn)行中的thread都有一個(gè)唯一的id值。
調(diào)用對應(yīng)的boost::thread對象的get_id()方法，或者在運(yùn)行的thread中調(diào)用boost::this_thread::get_id()方法。

Namespace this_thread
this_thread下包含的是在正在運(yùn)行的線程內(nèi)部，所能進(jìn)行的線程操作，包括上面提到的get_id()方法

Thread Group
thread_group class provides for a collection of threads that are related in some fashion.
New threads can be added to the group with add_thread and create_thread member functions.
thread_group is not copyable or movable.
