Mmmm interesting.

First it loads
dlopen: /Users/johnmci/Documents/Squeak3.8.0/build/Development/ 
Plugins/LargeIntegers => 0

Then we go to sleep and just calls
ioRelinquishProcessorForMicroseconds() which calls aioSleep for looks  
like 20 milliseconds...
If I stop the VM and look at the process stacks.

(gdb) call (int) printAllStacks()
Process
156455740 >idleProcess
156450332 [] in >startUp
156450424 [] in BlockContext>newProcess

Then suddenly it after some minutes it loads the
BitBltPlugin and then the
B2DPlugin

and calls
primitiveShowDisplayRect
which triggers the building of the main window and display, because I  
don't build the window until it's required.

Stack now reads
