A showcase for a potential bug in nodejs.
This program starts a tls.Server, and then two clients, one using the
deprecated createSecurePair and the other using tls.TLSSocket. It just opens
the connections and wait for the different events to trigger. Each event leaves
a trace. It reproduces 2 cases per client (4 in total): one just opening the
connection (write: false) and the other opening the connection and
immediately writing an empty string to the socket. Therefore the 4 cases are:
- SecurePair-write-false
- SecurePair-write-true
- TLSSocket-write-false
- TLSSocket-write-true
In order to reproduce the run node main.js using different versions of nodejs
and observe the differences in behaviour through the traces left by the program.

All write-false cases fail and the write-true cases behave slightly different,
as one of them (SecurePair-write-true) never emit the secureConnection event.
