Timeout with hanging server is not observed

[yschimke]

from arctic import Arctic
a = Arctic('myhost:27116')
b = a.list_libraries()
b
[u'dimos.test']

kill -STOP the server

b = a.list_libraries()

Hangs indefinitely. n.b. if socket is open, but mongo not responding e.g. then 20 second timeout is observed.

essentially set a read timeout instead of a connect timeout

The default timeout values we use are here:
https://github.com/manahl/arctic/blob/master/arctic/arctic.py#L71
socketTimeoutMS
connectTimeoutMS
serverSelectionTimeoutMS

Their explanation is here:
https://docs.mongodb.com/manual/reference/connection-string/#server-selection-and-discovery-options

Question is how long we wait for a query response, given the TCP connection is established and alive.
i.e. application level timeout without receiving an ACK for the executed query
