Just in case it wasn't clear: the shutdown hook will execute if you send
a SIGTERM to your application. All you have to do is trigger "clean
shutdown" from within the hook, wait for it to complete and return once
it is "safe" for the JVM to proceed with shutdown.

Answering my own question.
I've dug through the source a bit and concluded that the simplest thing to
do is to create a start-up class.
This will call the "startup()" method in
'org.eclipse.core.runtime.adaptor.EclipseStarter'. It will then listen on
a port for a shutdown command and (when received), call the "shutdown()"
on the EclipseStarter class.
This should provide a "clean" way to shutdown an Equinox instance. It will
also allow lifecycle events to proceed in the normal way for Equinox and
all bundles that are installed.
I might also, have it re-route the io for the FrameworkConsole in order to
support a remote equinox console.
