Try something along the lines of:

class DaemonThread
{
private:

    int cfd_;

public:

    explicit DaemonThread( int connection_fd ): cfd_( connection_fd ) {}
    void run() { /* thread procedure */ }
};

void mainloop()
{
    while( 1 )
    {
        int fd = accept();
        boost::shared_ptr<DaemonThread> handler( new DaemonThread( fd ) );
        boost::thread th( boost::bind( &DaemonThread::run, handler ) );
    }
}
