jython-pexpect-zombie.py

# Minimal example of jython -i causing zombie processes when called via pexpect.

import pexpect

EXECUTABLE = 'jython -i'
PROMPT = '>>>|\.\.\.' # Python uses >>> prompt normally and ... when in multi-line structures like loops

proc = pexpect.spawn(EXECUTABLE)
proc.expect(PROMPT)
print "=================================================="
print proc.before

try:
    proc.close()
except pexpect.ExceptionPexpect:
    print "process %s may not have closed" % proc.pid
