New issue 2698: Suspected memory leak with pysnmp==4.4.1 on PyPy 5.9 only
(Python seems fine)

Edward Beech:
The code to reproduce is fairly simple- obviously you'll need PyPy 5.9
installed first as well as pysnmp==4.4.1.
```
#!python
from pysnmp.hlapi import SnmpEngine, UdpTransportTarget, ContextData,
ObjectType, ObjectIdentity, getCmd, UsmUserData, usmHMACSHAAuthProtocol,
usmAesCfb128Protocol
ITERATIONS = 65536
for i in range(0, ITERATIONS):
snmp_engine = SnmpEngine()
context_data = ContextData()
errorIndication, errorStatus, errorIndex, varBinds = next(
getCmd(
snmp_engine,
UsmUserData(
userName='some_username',
authKey='some_auth_key',
privKey='some_priv_key,
authProtocol=usmHMACSHAAuthProtocol,
privProtocol=usmAesCfb128Protocol,
),
UdpTransportTarget(
('some_host', 161),
timeout=5,
retries=2,
),
context_data,
ObjectType(ObjectIdentity('.1.3.6.1.2.1.1.5.0'))
)
)
print '{0}/{1} - {2}'.format(i + 1, ITERATIONS, varBinds)
del snmp_engine
del context_data
```
Under PyPy 5.9 memory use steadily increases until (in my experience) MacOS
crashes; in Python however, all seems fine.
I've also raised an issue on the [PySNMP Github
page.](https://github.com/etingof/pysnmp/issues/103)
