For various reasons, we have to hold our main fileserver (Sun 450, approx
1,000 simulataneous connections) back on the 2.0.x series (i.e. pre-tdb
version of connections) of Samba.  (All our other servers are nicely up at
2.2.3a.) 

Would this bug have affected 2.0.x ?  If so, has anyone attempted to
address this bug in 2.0.x (x >= 7)?  Anyone got any hints to assist me to
produce a fix for our local use?
