[Seaside] Re: Concurrent requests from multiple sessions

[Bob Arning]

So, it would be interesting to run a version of something I posted 
yesterday:

     | nums procs big |

     nums := OrderedCollection new.
     big := OrderedCollection new.
     procs := (1 to: 3) collect: [ : i |
         nums add: 0.
         [
             10 timesRepeat: [
                 [10000 factorial] timeToRun.
                 nums at: i put: (nums at: i) + 1.
                 big add: nums asArray asString,' ',Time now asString.
             ].
         ].
     ].
     procs do: [ : e | e forkAt: Processor userBackgroundPriority].
     big inspect

Three processes at the same priority - on Squeak and Pharo, time gets 
shared between the three somewhat equally. What happens in VAST?
