It means that the exact error message still cannot be sent to the user
if the OS reports it asynchronously via SO_ERROR.  If
NonBlockingConnectHandler received an Error**, we could for example
report the error class and/or message via a new field of the
query-migration command even if it is reported asynchronously.
