Actually, though this gets rid of the walkback, it's not as good an idea as 
(for instance) getting rid of the call and replacing the TextMorph in the 
label altogether with something that knows how to figure out its width.

maxWidth is a real problem with TrueType fonts, as they're cached, and having 
to scan through thousands of glyphs is a pain.

In the current (read: unreleased) version of Connectors I have gotten rid of 
this problem.

And though I've been saying this for a while, I will be releasing a new 
version of Connectors soon.

Meanwhile, I just posted a fix for this particular problem.
