I'm using Pyro to develop a distribuited system
running my integration test suite I've found a strange
behaviour
it seems that whenever I have a failed resolve or unregister on
a name server, the name server acts normally during its life
span, but when I shut it down... something remains up...
if, afterwards, i lookup for a name server python freezes
and if i try to start a new name server, the port look occupied
is this a Pyro issue? or is that just me, that I've lost something
important?
i'll attach the code that causes the freeze
thanks!
