sync: running multiple get() calls results in TimeoutError

example code:

from netsnmpy import netsnmp, session
from time import sleep
netsnmp.load_mibs()

sess = session.SNMPSession("127.0.0.1", version="v2c", community="public")
sess.open()

varbinds = sess.get(netsnmp.symbol_to_oid("sysDescr.0"))
sleep(20)
varbinds2 = sess.get(netsnmp.symbol_to_oid("sysName.0"))

sess.close()

Running this code returns a TimeoutError on the last call to sess.get()
