#108 orderlyShutdown of vat fails

[Steve Jenson]

You'll remember I said orderlyshutdown doesn't work. I
just rebuilt my test case, it doesn't work, but maybe
the problem is, I don't understand orderlyShutdown.
orderlyShutdown requires an argument, it looks from the
docs like null is ok, but perhaps not. As a minimum,
better documentation of the argument is required in the
javadoc at erights.org

here is both a rune script and the trace it creates
---- rune script -----

? def makeServer :=
<elang:interp.makeServerAuthor>.boot(<unsafe>)
# value: <makeServer>

? def source := "def adder(a,b) :any {return a + b}"
# value: "def adder(a,b) :any {return a + b}"

? def [farAdder, farScope, farVat] := makeServer(source)
# value: [<Promise>, <Promise>, <Promise>]

? def result := farAdder <- (2,3)
# value: <Remote Promise>

? result
# value: 5

? farVat
# value: <Vat newServerVat in <runs in newServerVat>>

? def shutResult := farVat <- orderlyShutdown(null)
# value: <Promise>
