Migrations might take some time.
In any case the RPC code just does 'sendto' followed by 'recvfrom'.
There is no timeout to adjust on the client side.
Shuveb's problem is that TCP doesn't gracefully handle the case where
the ethernet cable is pulled out. There may be a socket option which
helps for this.
That depends on your definition of graceful.
Shuveb's definition is that he wants the connection to fail & give an error
back to the app.
My definition is that TCP should keep retrying until I plug the cable back
in, so I don't get unneccessary failures if i'm just switching cables
around. Likewise if there's temporary outages anywhere else in the link
between the client & server.
