FTP Error - Previous Request Not Completed

[Andre Garzia]

Err, if you close it then you're really aborting it midway which will give
you a corrupted file on the server you're uploading to. There are many ways
around this, what I do is:

1) Use liburlsetstatuscallback call to create a routine that will receive
periodic status reports from liburl.
2) Maintain a download queue
3) if the callback receives a call that says that a file transfer is
completed, then pick the next one in the queue.
4) if there's a recoverable error such as a timeout, then I restart the same
transfer
5) if there's an unrecoverable error such as the server being hit by a
meteor, I gracefuly exit the routine

This way, there's no collision, I will only start a transfer when I trully
know that the previous one finished.
