Netfilterqueue dies unexpectedly

Because:

Compiled with a 4096-byte buffer for packets, so it probably won't work on loopback or Ethernet with jumbo packets. If this is a problem, either lower MTU on your loopback, disable jumbo packets, or get Cython, change DEF BufferSize = 4096 in netfilterqueue.pyx, and rebuild

I believe that when running iperf, to test the connection cannot handle the throughput and dies about 2-3 seconds into the test. This could also be due to the low CPU rate for consuming packets, but the buffer may be leading the unexpected closing.

using -n 100000 max, at 1000000 unexpected quit occurs from nsfqueue.run()
