Thanks for all the reticent help over the years, everyone.=A0 It's
been fun.=A0 Such a pity that that help seems permanently revoked,
like an untrusted capability.=A0 I must not have participated well in
the social context, but that is par for the course for folks with
Aspergers, I am learning.=A0 I just can't ever seem to say the right
thing and more often than not, I piss people off.=A0 The issue is I
truly just don't get it.=A0 <br>

I see.=A0 Could you comment on how a Vine (and
promise3Desc/far3Desc) get introduced into the machinery when a
followOn msg gets forwarded to a third vat?=A0 In my example,
redirectForTheAnswer sends getTheAnswer to Bob and returns a
RemotePromise, which receives a hashCode followOn msg, forwarded
to Bob.<br>

Mark, your instincts were right on, it seems.=A0 I
have an issue with my use of the Vine and on
reflection it makes perfect sense. I am bending the
send from Carol to Alice over to Bob, so as it is a
3-way interaction, I need a Vine.=A0 In analyzing ELi=
b
code, you have 9 references to the Vine's
constructor, while I only have 7 (minus an extra
unused constructor I have).=A0 It is going to require
some digging to unearth what I am missing, but the
direction is clear.=A0 The place it blows up is in my
ProxyResolver.resolve() method, as the WeakReference
has lost the ref.=A0 However, this is not where the
reference is maintained.=A0 I suspect it may be a lac=
k
of an IdentityManager.<br>
<br>
I republished my code to: <a moz-do-not-send=3D"true"
href=3D"https://github.com/tooantuh/pauwau"
target=3D"_blank">https://github.com/tooantuh/pauwa=
u</a>.=A0
The tests pass, though there is an issue with the
RefTests and TestPauwau2VatException, as well as
this issue affecting TestPauwau3VatFollowOnSend.=A0
Additionally, the presentation tests need to be run
one at a time as stopping and starting the
Introducers can step on each other.<br>
<br>
thank you,<br>
