doh runner.html gets multiple cursors when previous tests throws

[bill]

ContentPane?.html runs without errors but when activated via runtests.html there are errors in setHref_then_cancel

I'm getting an alert on a dojo.disconnect(endHandler) that it was already disconnected.

Looks like this

Hum, well as far as I can see, the problem is that doh.runner isn't "thread safe". I don't have a better word, although I know JS don't have threads, "event loop safe" doesn't sound very good.

Take this: ​http://archive.dojotoolkit.org/dojo-2007-08-10/dojotoolkit/util/doh/runner.html?testModule=dijit.tests.module

The problem here is this: dijit.tests._Templated throws a error in one of the async tests then continues with dijit.tests.widgetsInTemplate AND dijit.tests.Container

Then _Templated throws a error and then we have 3 "cursors" trying to run tests simultaneously, that isn't working very well...

So fixing this means patching doh.runner.js

 }

But I'm to chicken to do this so close to the 0.9 release, and it does seem to surface some problems (need to extend timeouts) in dojo.tests.module

So I think that it's safe to punt this ticket to 1.0, or if somebody with more brains than me takes a look. (Understanding doh.runner.js sure isn't easy)

Ok I talked to bill about this, and he wanted me to resassign this to you Alex.

I have some uggly testcases to develop/test against if you are interested
