After checking the git logs, I realized that this failure is actually
new since 11e9caff8: before that, poll_query_until passed the query
on the command line not stdin, so it wasn't vulnerable to SIGPIPE.
So that explains why we only recently started to see this.
The fix I proposed seems to work fine in all branches, so I went
ahead and pushed it.
