Description Tim Lebedkov 2009-05-11 10:59:43 UTC 
A simple use case for a ProgressHandle: deleting files
If we are deleting more than 1 file, switchToDeterminate(numberOfFiles) shows a progress bar, which is OK.
If there is only 1 file, the progress bar does not move and it looks like the operation failed. 
Another problem arises if 10 files should be deleted and the deletion of the file 6 takes too long (5 minutes). The
progress bar does not move for 5 minutes. 

In seems more useful to switch to the indeterminate state automatically in following cases and deprecate manual switching:
- number of steps is 1
- nothing has changed in the last 30 seconds (progress, title, hint)
