I'm sorry I wasn't clear enough.  I wasn't attempting to explain your
circumstance.  I was trying to state a general design principal using a
kind of Socratic method.

Windows workstations are notorious for not bothering to signal goodbye.
  There are MS KB articles about fine tuning Windows servers to avoid
exhausting resources because the workstations are like that.  It's not a
samba issue, it's a windows issue.  I only tried to explain why it is
the way it is because you used the bug word.

There has been a samba option for forever (since at least 1.x or beta)

deadtime = <minutes>

just so the sessions don't hang around forever.  I never tried setting
it to 1 min., but you could experiment.  But it doesn't work if an
application forgets to close a file or release a lock..

I never tried it, but it should be possible to script something with the
"root preexec" if this is really an issue for you.  But be warned -
there are legitimate reasons multiple users can be logged on to a samba
machine at the same time.

For example.  My wife is logged on a widows machine.  I connect with
remote desktop.

Samba version 3.0.28-0.1.95-1624-SUSE-SL10.3
PID     Username      Group         Machine
-------------------------------------------------------------------
 7207   ranger1$      machine       192.168.202.35 (192.168.202.35)
 7207   FOREST\doug   users         192.168.202.35 (192.168.202.35)
 7339   FOREST\cindy  users         192.168.202.35 (192.168.202.35)
 7207   FOREST\cindy  users         192.168.202.35 (192.168.202.35)
 7339   ranger1$      machine       192.168.202.35 (192.168.202.35)

There's nothing I know of to readily distinguish your circumstance from
this circumstance other than quiescence on the connection for a period
of time.
