Inspecting big arrays freezes the image

[guillep]

Inspecting arrays with >=1G elements freezes the image, in some cases it does not even respond to interruption.

To reproduce inspect (on an image with everything saved or things you don't care about):

Array new: 1024**3

I managed sometimes to interrupt (cmd+.) with 1GB, but it was impossible with 3GB

Array new: 1024**3 * 3

Also, same happens with big ByteArray
