Something odd is going on with the Tracer -- it produces an image somewhat
bigger than 6Mb, which starts up ok and saves back to 4-ish MB. Rather
spoils the 'coffee-break garbage collector' story doncha think? It seems to
be a recent problem, as older images clone same/smaller as appropriate. I
though it might be related to the Display size/depth, but seem to have
ruled that out. Maybe the WeakArrays need more careful cloning?

While tracking down prolbems with cloingetc, I found this pair of changes
useful:- it saves a bit of time when looking for method versions by not
opening a browser if there is only the one version. I'm sure it could be done
more prettily...
