I had actually forgotten that this was still open. Anything I can do to
help speed this along?

In case nobody remembers, the purpose of this was to provide a facility
to embedded applications that allows for a more graceful shutdown in
fatal error situations. My original use-case was for a PostgreSQL PL
extension where an abort() is quite undesirable as it would take down
the entire cluster(yeah, all the postmaster processes).

IIRC, the only thoughts "against" it were rather for trying to remove
FatalErrors entirely.
