Currently the timeout and retries are hard-coded in an inaccessible variable in SNMPImpl.java

static final int RETRIES = 1;
static final int TIMEOUT = 500;

changing these would require subclassing SNMPImpl

Pending a more formal configuration mechanism, perhaps these could be made public static (non-final) so they can at least be altered globally?

We're experiencing fairly regular connection timeouts when performing GETBULK on our particular machines. We do not experience this issue nearly as often (it does happen though) with the command-line snmpwalk from net-snmp 2.6, which for reference, has default RETRIES = 5 and TIMEOUT = 1000.
