Comment 18 for bug 412413

I tested the fix under Ubuntu 9.10 i386 and fix looks OK. I was able to download these DVDs (from LAN source):
ubuntu-9.04-dvd-i386.iso
ubuntu-9.10-dvd-amd64.iso
ubuntu-9.10-dvd-i386.iso

I tried full or partial download, all my test passed.

After that I tried to download a huge file, (isomix.bin, 5.5GB) and found no problem; I tried full and partial download.
isomix.bin file was created in this way:

$ cat u*server*iso u*alter*iso > isomix.bin
$ zsyncmake isomix.bin

$ ls -ltr isomix.iso*
-rw-r--r-- 1 root root 5599563776 2009-11-07 03:09 isomix.bin
-rw-r--r-- 1 root root 12303881 2009-11-07 03:22 isomix.bin.zsync

$ ls -l u*server*iso u*alter*iso
