Transport is_open() doesn't return False after closure

[gorlins]

Version 0.3.8 python 2.7, transport.close() either does not close the transport or incorrectly returns its status

from thriftpy.thrift import TClient
from thriftpy.transport import TFramedTransport, TSocket
from thriftpy.protocol import TCompactProtocol

_transport_class = TFramedTransport
_protocol_class = TCompactProtocol

socket = TSocket(host, port)
transport = _transport_class(socket)
protocol = _protocol_class(transport, decode_response=False)

print 'Transport open:', transport.is_open() # False
transport.open()
print 'Transport open:', transport.is_open() # True
transport.close()
print 'Transport open:', transport.is_open() # True!!
transport.open()
print 'Transport open:', transport.is_open() # True
