On a Windows XP system with the following type of directory, for a music folder
defined to c:\music:

c:\music\artist X\album Y

If a link/shortcut file is placed in the above direcory linking to album Y such
as "c:\music\artist X\album Y\shortcut to album y.lnk", slimserver will go into
an infinite loop consuming all of system memory and eventually crashing.

Now, I know, why would anyone do such a thing? My fat thumbs have done this on
more than once occasion (5 or 6) for over a year now.

A service/application should not consume all system resources and crash, if a
user made an error definning the data (directory structure).

Additional error checking proposal(s): One possible solution would be to keep
track of link/shortcut files, and if a file is read more than once, it should be
ignored. Or, if a directory structure has already been processed, it should be
skipped during the single scan process.
