segments are lost for the application. This broke, for example,
ports/benchmarks/dbs which needs the SYN segment to filter the
contents of the trace buffer for the connection it is interested in.
This patch makes the SYN segments available again. Unfortunately they
are now associated with the listening socket instead of the new one, so
a change to applications is required, but without this patch it wouldn't
work altogether.
