Description (last modified by viboes) 

bool thread::start_thread_noexcept(const attributes& attr)
    {
new_thread=_beginthreadex(attr.get_security(),attr.get_stack_size(),&thread_start_function,thread_info.get(),CREATE_SUSPENDED,&thread_info->id);
    }

If the STACK_SIZE_PARAM_IS_A_RESERVATION attribute is not set in createthread, stack size does not take effect

The default stack size (1M), win32 can start the number of threads is about 1400 or so, set the stack size of 256K, the number of threads that can be enabled should be far greater than 1400, but the actual test found inaccurate, set STACK_SIZE_PARAM_IS_A_RESERVATION only after Achieve the expected results.
