In [6]: mylist = [1,2,3]

in the proxy the stale connection is being "removed" on error, but it causes one of the remaining connections to miss a chunk.

In [7]: mybytes = ['a', 'b', 'c']

In [8]: for byte in mybytes:
   ...: for conn in mylist:
   ...: if conn == 1:
   ...: mylist.remove(conn)
   ...: print byte, conn
   ...:
   ...:
a 1
a 3
b 2
b 3
c 2
c 3
