Mark,

You are absolutely correct in your analysis. I must have overlooked the
behavior of Net-SNMP's snmpwalk tool when implementing its Python
version.

I'm going to fix snmpwalk.py to make it acting more similar to
snmpwalk. This might take a few days. Will let you know then.

Meanwhile, I suggest you to try using the examples/snmptable.py tool
which, at least, stops as it walks out of the initial sub-tree:

[ilya@cray examples]$ ./snmptable.py ts29.moscow.st.net public
.1.3.6.1.2.1.1.1
.1.3.6.1.2.1.1.1.0  --->  'Cisco Internetwork Operating System Software
\015\012IOS (tm) 5400 Software (C5400-JS-M), Version 12.2(11.8b),
MAINTENANCE INTERIM SOFTWARE\015\012Copyright (c) 1986-2002 by cisco
Systems, Inc.\015\012Compiled Tue 30-Jul-02 19:02 by pwade'
[ilya@cray examples]$

Please, note, that snmpwalk.py/snmptable.py starts from the N+1 variable
in the MIB so you would have to give it the N-1 variable to fetch N-th.
Since snmpwalk seems to start from N, I would probably also have to fix
it in snmpwalk.py tool.
