Proper error handling when sending XMPP message

[jedlau]

Recently, SendXmpp() started failing for me with the following error:

write tcp <IP>:<port>-><IP>:<port>: write: connection timed out

Restarting the Go process that called SendXmpp() makes this error go away, and push notifications start working again. But of course, restarting the Go process isn't ideal. Is there something I can do explicitly to handle this kind of error? For instance, is there a way to close the current XmppClient and retry sending the message, so that the retry instantiates a new XmppClient and opens a new connection?
