Ok...this is just, well, fun, but I can't quite figure out how to get a second image loaded with the #doIt channel "working."  I figure it's because I don't have the image I created it from set up right?  All I did was go down the line of in the Helpful doits workspace:

"Sanity check, are we running HydraVM?"
HydraVM isHydra  [true]

"To prepare an image for running in background thread (careful, VM will quit if you run this)"
HydraVM saveAsHeadlessImage: 'test.image'  [current image shut down and created another image]

"To run previously prepared image"
HydraVM loadAndRunNewImage: 'test.image'  [seemed to work]

"How many interpreters VM currently running"
HydraVM interpreterInstanceCount [2...this is good!]

"Test to check if main image listening for #transcript channel ..."
HydraChannel send: 'Transcript test' to: (HydraInterpreter current) channel: #transcript [true after the following line]

"... if not, try doing this first: "
HydraTranscript install

"Simple test to check if second image listens #doIt channel "
HydraChannel hasChannel: #doIt at: (HydraInterpreter at: 2)  [false]

Drat!!!

" ... and has Transcript global var replaced to redirect all input to main image"
(HydraInterpreter at: 2) doIt: 'Transcript show: ''Doit Test'''

"Do you like to install something to secondary image?"
(HydraInterpreter at: 2) doIt: '(HTTPSocket httpGet: ''installer.pbwiki.com/f/Installer.st'') fileIn '

"Do you like to save it? "
(HydraInterpreter at: 2) doIt: 'Smalltalk snapshot: true andQuit: false '


Take care,

Rob
