Bug in new memory system?

The postmaster doesn't seem to want to shut down cleanly with active
connections anymore.

Start up a server, start up a connection (say, psql), press Ctrl-C in the
server window.

The reason I'm saying "bug in memory system" is this backtrace:

201             while (context->firstchild != NULL)

There are no such problems when there are no connections open at the time
of the shutdown.
