if you use a SocketChannel instead, you'll be able to deal with ByteBuffers
directly instead of going through byte arrays.

Could you drop the delayed queue, and instead send user_canceled/close_notify
before you start reading from the socket? It would simplify the code and
improve the coverage.

Make sure to read until EOF

could you split the write and read methods?

limit() - position() is equivalent to remaining()

this method might return a partial TLS record or multiple records. SSLEngine
expects to receive the entire record in one buffer.
