Seems to me that if we have "detach()," it we should be asking whether a thread is "attached()," rather than "joinable()." Our documentation
Agreed.
says "if *this refers to a thread of execution..." all over it, which would seem to indicate that joinable() is an important question even when you're not about to join().
I find this phrasing a bit strange. 'thread of execution' sounds like a concept. Is the 'main' thread not a 'thread of execution' ? (And even if no threads are spawned at all ?)
The 'main' thread us a thread of execution, even if no other threads have been spawned. You cannot obtain a boost::thread object that references it though.
If what is referred to is actually an object (as hinted to by the use of '*this', it should be clear by use of an appropriate (type) name ('thread', instead of 'thread of execution').
The *this in question refers to the boost::thread object on which a member function is being called. A boost::thread object may reference a thread of execution (whether running or finished), or it may not reference anything (e.g. a default-constructed boost::thread object).
