Simple testcase:
1. install uTorrent
2. verify in uTorrents advanced settings that diskio.sparse_files is set to
false
3. load a torrent and start it

As soon as uTorrent has one piece completed it will create the to-be-downloaded
file with target filesize. Then it will write piece data into the file.

Under Unix the above results in having a sparsefile that is filled with piece
data in order of download (which in the end gives a fragmented file) while
under Windows this results in having a normal 'preallocated' file.

The unix sparsefile can be verified by running 'ls -ls $FILENAME' and the
Windows normal file can be verified in various places (explorer, increased
diskusage, file-properties, etc...).

If you do not want to install uTorrent, i can also give you a complete trace,
but i don't think you will gain more information than what can be read from the
attached trace already.

BTW: how can this bug be linked to the AppDB? Currently uTorrent is listed with
platinum status.
