thread detach -- boost ^ java

In most (if not all) systems, a thread object is a "poor handle" on a real world thread.

in java, if the thread object becomes unreachable (and garbage collected) then you can't join or interrupt the thread, or test if it holds a particular lock. You have to wait for it to finish or pull the plug with System.exit().

Same scenario exists in boost thread. Additionally, boost lets you explicitly call myThread.detach(), to decouple the myThread object and the real world thread.

Q: after detach(), what's the thread object?
A: it represents not-a-thread
