Summary: ThreadingTCPServer file handle errors.

Initial Comment:
When running a server using ThreadingTCPServer if the
server sit for several minutes between requests the
first request it receives will error with a bad file
handle error.

Python 2.1 (#1, Apr 20 2001, 15:04:11) 
[GCC 2.96 20000731 (Red Hat Linux 7.0)] on linux2

#!/usr/bin/python2

from SocketServer import ThreadingTCPServer,
BaseRequestHandler



class myHandler (BaseRequestHandler):
    def handle(self):
        while 1:
            data = self.request.recv(1024)
            if not data: break
            
            self.request.send('%s' % (data))
            
        self.request.close

if __name__ == '__main__':
    addr = ('localhost', 50000)
    s = ThreadingTCPServer(addr, myHandler)
    s.serve_forever()

Start this server wait several min then
using the echo-client.py from oreilly Programming
Python to 
send it data.

Traceback (most recent call last):
  File
"/var/tmp/python2-2.1-root/usr/lib/python2.1/threading.py",
line 378, in __bootstrap
    self.run()
  File

    self.handle()
  File "./server.py", line 10, in handle
    data = self.request.recv(1024)
error: (9, 'Bad file descriptor')

Any requests sent right after this will complete
properly.
