Kapil Thangavelu updated ZOOKEEPER-768:
---------------------------------------

        Summary: zkpython segfault on close (assertion error in io thread)  
(was: zkpython segfault (assertion error in io thread))
    Description: While trying to create a test case showing slow average 
add_auth, i stumbled upon a test case that reliably segfaults for me, albeit 
with variable amount of iterations (anwhere from 0 to 20 typically). fwiw, I've 
got about 220 processes in my test environment (ubuntu lucid 10.04). The test 
case opens a connection, adds authentication to it, and closes the connection, 
in a loop. I'm including the sample program and the gdb stack traces from the 
core file. I can upload the core file if thats helpful.  (was: While trying to
