Well, this code is running on all my servers, and they aren't hitting it. 
I was only able to trigger it when putting OpenLDAP under extremely high 
load, and adding SASL/GSSAPI into the mix.  If I am missing patches, it 
isn't in connection.c or daemon.c.  Not sure where else to look past that. 
;)  I'll see if I'm able to reliably reproduce it or not.  If not, I'd 
guess it is a race condition of some sort somewhere...
