16,way to defer thread creation needed,nobody,nobody,"{{{
It is not now currently possible to defer boost thread creation to a later time without creating a 
wrapper class for the thread class.  Starting a thread immediately in a constructor is not always 
desirable.  Sometimes you require other members in your class to be initialized before the thread, 
for example.  Or perhaps your class may have many threads that have to all be initialized before 
any of them can be created.  

I propose a new member function: thread::start(const function0<void>& threadfunc) to accomplish 
this goal.  To use this new function you could do something like:

   boost::thread thrd; // notice no function specified
   thrd.start(thread_alarm(secs));

or perhaps thread::start() could take no parameters and an new alternate thread constructor could 
be added that would not execute the thread right away:

   // thread class could have an enum { execute, defer } 
   boost::thread thrd(thread_alarm(secs), boost::thread::defer);
   thrd.start();

The latter form has the advantage of the caller of start() need not being concerned with what 
function is being invoked.
