This could be due to a change in the Sockets in Pharo, that's maybe
why other people do not see it. It is definitely a bug to get
debuggers.

I don't have time to investigate further right now, but I guess
somebody will come up with a fix quickly :-)

Still - it would seem that by signalling this - it could happen, and
something should catch it?

Looking again, I see the following method in the stack:

WAListenerAdaptor&gt;&gt;waitForConnection: aSocket
&nbsp; &nbsp; &nbsp; &nbsp;| socket stream |
&nbsp; &nbsp; &nbsp; &nbsp;socket := aSocket waitForAcceptFor: 10.
&nbsp; &nbsp; &nbsp; &nbsp;socket isNil ifTrue: [ ^ self ].
&nbsp; &nbsp; &nbsp; &nbsp;stream := SocketStream on: socket.
&nbsp; &nbsp; &nbsp; &nbsp;[ [ [ self process: stream ]
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;ensure: [ stream close ] ]
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;ifCurtailed: [ socket destroy ] ]
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;forkAt: Processor userBackgroundPriority


Shouldn't that ifCurtailed: prevent this walkback?

It doesn't prevent the walkback, but makes sure that "socket destroy" is
called. Experiment with:
[Error signal] ifCurtailed: [Transcript show: 'Abandoned'; cr].
Transcript show: 'Proceeded'; cr
