I can't speak on behalf on Juergen, but I'll give my understanding of
it here.

I looked at the code in the 3.0 snapshot, and the socket code looks
pretty much the same as 2.1.x. I would say the current version
requires quite a bit of re-engineering in order for it to work with
threads. Some of the hurdles include:

- there are only 2 sockets: one for trap and one for SNMP requests.
The synchronous socket recv code is definitely not thread-safe.

- static/global variables. Some of them can be shared, like static
lookup tables.

- the mib command needs synchronizations in accessing the parsed
mib structures.

There must be others.

It sure would be a desirable thing to have, but I also understand that
this is free software.

I think this would make a wonderful student project/thesis.

Hi All,

is the Scotty Distribution thread safe and will it work
with the new Tcl alpha release 8.1a2 (beyond known bugs).

regards
Chris
