[AGENT++] AgentX subagent: connection lost when signal arrives

[Frank Fock]

Hi Rüdiger,

Thanks for the fix. It will be part of the next AgentX version
which is scheduled for release next week. That version will also
include other fixes posted here that might not have been commented
(Sorry).

SNMP++, AGENT++ and AgentX++Win32 will also be updated
soon.

Best regards,
Frank
