Re: constructing and initializing a scoped_array

I have some old code that I am refactoring to use smart pointers and
have run into a small problem. My original code looks something like
this:

class WorkerThread
{
   std::map<int, Handler> &HandlerMap;
public:
   WorkerThread( std::map<int, Handler> &AHandlerMap )
       : HandlerMap( AHandlerMap ) {}
};

WorkerThread *WorkerThreads[MAXTHREADS];

for ( int i=0; i<MAXTHREADS; i++ )
{
   WorkerThreads[i] = new WorkerThread( TheHandlerMap );
}

And I think I'd like to change it to use a scoped_array:

boost::scoped_array< WorkerThread > WorkerThreads;

WorkerThreads( new WorkerThread[/*...*/] )

Unfoortunately, the WorkerThread class does not have a default
constructor, and as such, the compiler does not allow me to cosntruct
a scoped_array. So maybe a scoped_array isn't the way to go, but it
seemed like most obvious choice. What would be an appropriate
solution?
