Hi,

Sorry for being a little late in replying.

The progressbar implementation is excellent but it has the same problems that 
the current progressbar implementation I use, has.

In the above mentioned progressbar implementation also, the progressbar status 
is overwritten if you're using multiple threads.

If your application is threaded, and multiple threads are downloading multiple 
files, you get a progressbar which is overwritten by all the 3 threads.

I had brought this issue some time back too.
Dennis Lee Bieber had a solution which looked better but not very much. His 
implementation had os.system(clear/cls) being called (to update the progress) 
which made the screen flicker if your network latency was low (especially in 
cases where the data is indirectly being downloaded from a Proxy or a product 
like NetApp's Netcache).

If there's a way to print multiple lines of text withouth the newline ("\n") 
character, we can then use carriage return ("\r") and implement a proper 
progressbar with a bar for each separate progress action.

Thanks,
Ritesh
