Note that the krb5 library may call support routines in the C library
or other libraries (gmtime, gethostby*, getpw*, etc.) which may not be
thread-safe.  Getting us thread safety for real requires a pass
through the library to make sure all such cases are fixed.

I suspect there may also be some issues with file locking in multiple
threads, but I haven't investigated that.
