Please send replies with subject line pending/883. Note that merely
sending to krb5-bugs won't get you an ack, since it has to be
manuallly processed in that case, and we tend to be able to process
bugs sent by way of krb5-send-pr more efficiently.

I'll send more in the correct PR.

Hi all:

I never got a reply to this message. Can anyone give me any information on

Even an ack "Yes it's a problem" or "never heard of it" would be helpful.
