Imagine this timeline:

<thread1> os.environ['__kabc_ldap'] = '/tmp/tmp1'
<thread1 suspended, thread2 starts to run>
<thread2> os.environ['__kabc_ldap'] = '/tmp/tmp2'
<thread2> launch ldapsearch (output goes to '/tmp/tmp2')
<thread2 suspended, thread1 starts to run>
<thread1> launch ldapsearch (output goes to '/tmp/tmp2' over output
from ldapsearch launched from thread1)

Seems like that's what is happening to your program.
