Then some latent packet traffic shows up well after the close.

Can you define "well after".  Are we talking milliseconds?  Seconds?  I'd like to try this out myself, but I need to know what I'm looking for.

Be aware that closing a TLS connection results in traffic being sent on the wire [1].  If the network has failed, or the remote peer is misbehaving, that can cause long delays between your close and the final close of the TCP connection underlying the TLS connection.

Up to five minutes.

I'm profiling when this does and doesn't happen for us.

We're currently SSLv2 using some relaxed settings.
