  Hmm... it could be an ntlm_auth issue.  Maybe moving to pipes as Phil
suggested would help.

 In any case, it's not new in 2.2.1.  So I think it's time to release 2.2.2.

  Set the exec timeout to 1s.  It should take less than a second to run
ntlm_auth.  If it takes more than a second, something is wrong.  And
you're probably better off dropping the connection than waiting 30s for
a timeout.
