Ah. Now I think I get it ......

The new Microsoft redirectors use the "feature" of Microsoft SMB
implementations that SessionSetup SMB with the VC number set to 0
should terminate all previous sessions from the same client, 
they don't bother to send a Logoff command any more.

We can change Samba to send all connected SMB's a "disconnect"
message when we get a new VC=0 SessionSetup to fix this I think.

I will investigate further.
