With care.

As mentioned in the earlier "thread-safe" FAQ entry, the Net-SNMP
agent (including the AgentX subagent) has not been designed for
threaded operation.  In particular, it makes use of various global
variables without attempting to protect them against simultaneous
use.  This means that it is '''NOT''' safe to have SNMP or AgentX
related processing in two separate threads.  This also applies to
handling GET (and SET) processing in one thread, and generating traps
in another.  This is still vulnerable to the usual threading problems.

However, as long as '''all''' of the SNMP-related activity is limited
to the one thread, then there should be no reason why this cannot
safely communicate with other threads within the same application,
using private (thread-safe) mechanisms.

But in terms of the Net-SNMP-provided code, the agent (and AgentX
subagent) should '''not''' be regarded as thread-safe.
