Yes.
If you look at the code (in snmplib/snmp_client.c), it boils down
to the following:
int
snmp_synch_response_cb(netsnmp_session * ss,
netsnmp_pdu *pdu,
netsnmp_pdu **response, snmp_callback pcb)
{
snmp_send(ss, pdu);
while (state->waiting) {
snmp_select_info(&numfds, &fdset, tvp, &block);
select(numfds, &fdset, 0, 0, tvp);
snmp_read(&fdset);
}
}
(where the callback routine 'snmp_synch_input' clears the waiting flag).

Exactly.
