Increasing guest memory in Vancouver

Hi Norman,

what's life without adventures? ;)

I used run/vancouver as starting script, yes. And I noticed that
increasing to something around 90 MiB works without problems. Going
beyond that (e.g., 100MiB) strange things happen like page faults
where there should not be ones, or for example an INT 3 debug
instruction which seems to "forget" about the parameter it was passed.

But with my current configuration I am able to proceed, although it
would be interesting to know what happens with more memory.

I did not run into that other issue you mentioned, not that I remember.
