Indeed, it doesn't.  The logs don't offer much, and I am not sure if
this is a problem that happens when opening the first segment, or if
that's the first write.  The starting position is good:
pg_receivewal: starting log streaming at 0/2000000 (timeline 1)

fairywren did not run the first round of those tests in ffc9dda,
perhaps that's a different issue than what bowerbird has reported.

The backend logs don't tell much either, but that certainly looks like
a crash:

Could it be possible to get a backtrace?  I won't let this enabled
much longer, just waiting for bowerbird to tell more.
