Wouldn't help anyway, if some other part of the app also calls kerberos.
I think we should just state that kerberos isn't thread safe and it
isn't our problem.
For the same reason, the mutex in (eg) pqGethostbyname is an utter waste
of code space. It guarantees nothing. Furthermore, any machine that
claims to have a thread-safe libc will have either gethostbyname_r()
or a thread-safe implementation of gethostbyname(). There is no value
in our second-guessing this.
