Nice work!

I was going to plead with buildfarm owners who use --enable-tap-tests to
update sooner rather than later, because this separate-logging behavior
is going to make it a lot less painful to decipher failures during the
TAP tests. However, in view of my results in
https://www.postgresql.org/message-id/21358.1492622881%40sss.pgh.pa.us
I can't really recommend that owners of slower machines update just yet.
Hopefully we can do something to trim down the added runtime.

These things are pretty cool, but maybe they need to be documented at
https://wiki.postgresql.org/wiki/PostgreSQL_Buildfarm_Howto
