Debug statements

So is there a problem or not? ;-)
If there is, you find attached a patch that outputs debug messages from main
thread and loading thread. Output should look like

digikam: MainThread: ManagedLoadSaveThread::load, creating load request for
/media/fotos/Andalusien 2004/pict0053.jpg
digikam: Main thread: Now leaving ManagedLoadSaveThread::load
digikam: Loading image in thread
digikam: Doing the real work in thread, loading /media/fotos/Andalusien
2004/pict0053.jpg
digikam: /media/fotos/Andalusien 2004/pict0053.jpg : JPEG file identified

digikam: Received event of type 1000
digikam: Main thread: This is the loaded event. Now the signal is sent from
LoadSaveThread
digikam: Main thread: DImgInterface::slotImageLoaded. The image data has
arrived, now display it

It's most interesting if you observe delays and watch the console at the same
time to see when the delay occurs.

Btw: The image editor does _not_ use the digikampreview ioslave. What you
observe is: When you change the picture in IE, it notifies the main view, which
marks the new picture as active, which triggers the start of the preview
ioslave.
