[AGENT++] Crash in multi-threaded SNMP++ use (usm_v3.cpp:1262)

Hi,

after looking (and currently fixing this issue) I can say that users are
not removed safely, or more precise: other threads can use already
deleted data of removed users.

So you're safe, if you only add new users.

Also I saw that my suggested workaround does not help for the case where
 a message is procecced while the user is removed.

We don't have a list of known bugs/issues, as following this list should
show all issues since the last release.

Nevertheless daily snapshots of snmp++ and agent++ will soon be
available, so a look at the snapshot CHANGES file will show all issues.

Regards,
