Browsing a long method (lets say, of ~270KB of sourcecode) just hangs the image.

Interrupting doesn't even give me control over my image again.� It does no open a debugger, but info is printed in stdout, so I assume that my UIProcess died, but the event fetcher is still alive...

One of the processes that get interrupted prints:

SmallIdentityDictionary(SmallDictionary)>>at:ifAbsent:
MorphExtension>>valueOfProperty:ifAbsent:
MorphExtension>>valueOfProperty:
ScrollBar(Morph)>>valueOfProperty:
ScrollBar(Morph)>>theme
ScrollBar>>normalThumbFillStyle
ScrollBar>>adoptGradientColor:
ScrollBar>>sliderColor:
ScrollBar>>adoptPaneColor:
PluggableMultiColumnListMorph(Morph)>>adoptPaneColor: in Block: [:m | m adoptPaneColor: paneColor]

So I just changed #adoptPaneColor: in ScrollBar to do nothing, and I am able to interrupt again. So it makes me think here it is where the UIProcess gets killed...

Now, for the browser stuff, it seems that TextComposer>>#composeAllLines never finishes.� I'm still investigating, but any clue is helpful :).
