I want to know how does nodejs driver behave when PRIMARY GOES DOWN.
Issue db.shutdownServer() on Primary
"SECONDARY" become Primary right away.

But driver takes at least 11 second hanging before issuing another write command again.

I test with various number for connectTimeoutMS & socketTimeoutMS & haInterval
But it does not help.

Connection String:

"mongodb://xxx:xxx@1.10.21.67:27017,1.10.21.98:27017/test?replicaSet=hhawsmongo&poolSize=1&autoReconnect=true&reconnectTries=100&connectTimeoutMS=1000&socketTimeoutMS=1000&haInterval=500&forceServerObjectId=true"
