  Okay I reproduced this, (as user i.e. using the proxy) I will chase it
down should be easy, probably the file descriptor is not reset on Close.
And I will ad a python test for it,

  thanks for raising this, did you got the problem as root ? It seems to
work for me as root, i.e. being a problem when reconnecting with the proxy.
