Yay ! I think the smb9 valgrind trace has the info I need to fix this bug....

==16948== 868,800 bytes in 200 blocks are definitely lost in loss record 60 of
60

The "868,800 bytes in 200 blocks are definitely lost" is a bit of a give-away,
and this is also an area that changed between 3.3.x and 3.4.x. Thanks a *lot*
for this.

More once I've isolated the bug....

Jeremy.
