The debug build that never died

Since yesterday, I have been annoyed by a strange phenomenon.

The debug build is not deleted consistently. As a result, when I run, I get the message of Compilation failure, asking if the debug is not running.

Of course, that would be too simple if it happened all the time. It is elusive. But it seems to happen more often when the debugging messages is displayed. Possibly when some JavaScript is still processed in the HTMLViewer.

a) This has been happening since forever. Sometimes the app is deleted, sometimes not.
b) Write yourself a shellscript to delete the debug app before building.

I never encountered it before. Guess I was lucky.
