uwsgi环境下，thread执行疑难问题，求解！

在Python环境下做了一个利用线程异步执行的程序，但是http访问的request对象经过线程建立后传入总是有问题，其中的META经常是空的，偶尔会出现完整的情况，而且在生产环境下测试还会出现传入前后不一致的现象，fastcgi模式就没有问题，到底是什么原因呢？

代码：
import uwsgi
class ThreadSchem():
def __init__(self, *args, **kwargs):
self.args = args
self.kwargs = kwargs

def execute(self):
print self.args
print self.kwargs

def run(self):
import threading
print uwsgi.worker_id()

T = threading.Thread(target=self.execute)
T.setDaemon(True)
T.start()

class TS(ThreadSchem):
def execute(self):
print uwsgi.worker_id()
print '=================='
print 'args:'
print self.args
print '=================='
print 'kwargs:'
print self.kwargs

def after_browsing(request):
print 'request:'
print request
Schem = TS(request)
Schem.run()

return HttpResponse('')

运行结果：
