[Samba] Slow listing of mapped drives in Explorer

[tim at ccmp.ox.ac.uk]

Issue solved.

Well more of a work around really. I used apt pinning to to pull the
latest Samba 3.2.4 package from Debian testing (Lenny) instead of 3.0.24
which currently ships with Debian stable (Etch). Version 3.2.4 doesn't
immediately disconnect clients the way 3.0.24 does.

Still not clear whether this is a Debian introduced 'problem/feature' or a
consequence of the 3.0.24 source itself.
