Good use of while read. You can redirect the entire loop instead of reopening download.txt 1000 times though:
wget also has some features which make a loop unnecessary though
wget is able to read a list of files with -i. The -nv option is also useful, to make it still print completed files without printing all the complicated junk wget usually does.
This should be much faster than calling wget 1000 times since it is able to re-use the same connection if it's connecting to the same site. Concurrency may not be necessary ( and may not be desirable in many cases -- how fast is your connection? ) but if it is, I'd split the list into parts and use wget -i on those parts.
Good day!

KETCHUP(1) General Commands Manual KETCHUP(1)NAME
ketchup - Utility to update the kernel source
SYNOPSIS
ketchup [options] <ver>
DESCRIPTION
This tool synchronises a local kernel tree with a desired kernel version and patch set from a kernel.org mirror. The default requires a GPG
key on your keyring, to verify the identity of the patches and source archives. Entire kernel images are not downloaded unless necessary,
so bandwidth is saved. Patches are applied and removed as necessary to attain the requested version.
OPTIONS -a --archive (~/.ketchup)
cache directory
-d --directory (.)
directory to update
-f --full-tarball
if unpacking a tarball, download the latest
-g --gpg-path (/usr/bin/gpg)
path for GnuPG
-G --no-gpg
disable GPG signature verification
-k --kernel-url (http://www.kernel.org/pub/linux/kernel)
base url for kernel.org mirror
-l --list-trees
list supported trees
-m --show-makefile
output version in makefile <arg>
-n --dry-run
don't download or apply patches
-o --only-dl
don't apply patches
-p --show-previous
output version previous to <arg>
-q --quiet
reduce output
-r --rename-directory
rename updated directory to linux-<v>
-s --show-latest
output the latest version of <arg>
-u --show-url
output URL for <arg>
-w --wget (/usr/bin/wget)
command to use for wget
CONFIGURATION
Ketchup will read files named .ketchuprc in $HOME and in the target kernel directory, with the kernel directory taking precedence.
A .ketchuprc file uses the Python syntax and may set the following variables:
default_tree
The default_tree option specifies the kernel version to work with if one is not given on the command line.
precommand
The precommand option specifies a command to run before synchronising the kernel tree to the required version.
postcommand
The postcommand option specifies a command to run after synchronising the kernel tree to the required version.
