TITLE:
hudson slave-agent (slave.jar) shold not exit when network is missing:

PROBLEM:
currently, when slave-agent runs on start insde a vmware guest,
there are times when java (slave-agent) is started/running,
while vmware network is still not ready;

this causes slave-agent to exit on IOException - see sample hudson.log below;

SOLUTION:
slave-agent code should continue to try to connect after a delay;

WORKAROUND:
1) introduce startup delay
2) intruduce slave-agent dependency on other networked service
