kick off CI

If a TLS error occurs, it could end up in a situation where the network handler code did not want to
read or write because it only had the error flag set. However, this was not handled, which left the
socket triggering in the event loop - but nothing was done to handle it.

This can easily cause a 100% cpu situation - the hub is still functioning though while this is
happening.

+ *
+ * Prefix an argument with ? to make it optional.
+ * Prefix with + to make the argument greedy, which causes it to grab the rest of the line ignoring boundaries (only supported for string types).
+ *
+ * NOTE: if an argument is optional then all following arguments must also be optional.
+ * NOTE: You can combine optional and greedy, example: "?+m" would match "", "a", "a b c", etc.
+ *
+ * Example:
+ * "nia" means "nick cid ip"
+ * "n?p" means "nick [password]" where password is optional.
+ * "?N?N" means zero, one, or two integers.
+ * "?NN" means zero or two integers.
+ * "?+m" means an optional string which may contain spaces that would otherwise be split into separate arguments.
