Maybe the right answer here is a "slewed parallel" connection
establishment; start with one address, and if you get a soft error or
a RTO-sized timeout, try a second, third, fourth, etc., connection,
but leave the prior ones open in the event they complete successfully.

Soft errors wouldn't kill the first connection -- they'd just be a a
hint to try another connection in parallel.

This should probably be buried in a library routine so that
applications don't have to reinvent this wheel.
