The pcap.pcap() will blocked when it run in thread with twisted and wxPython

[GoogleCodeExporter]

import threading
import pcap

import wx
from twisted.internet import wxreactor
wxreactor.install()
from twisted.internet import reactor

def run():
    import pcap
    p = pcap.pcap() # we blocked here!
    print 'Created pcap'
    for ts, package in p:
        print ts, len(package)

reactor.callInThread(run)
reactor.run()

This piece of code reproduce the problem.

I believe this blocks because you don't call p.setnonblock(1) before trying to 
read packets. This can probably be closed.
