In git commit 49470ac38, on 2016-02-08, we added a -1 option to spiped, which causes the server to quit after one connection stops. This was added to simplify our test suite. However, thanks to Tim Düsterhus's "Perform a graceful shutdown on SIGTERM" (git commit 8f22fea04, on 2016-05-08), we no longer use -1 in the test suite.
-1 has never appeared in an official spiped release, and we're considering removing it. Would anybody prefer it to remain? Cheers, - Graham Percival
