When mirroring from a fast mirror over a slow link
anonftpsync can hog all the bandwith, to the detriment
of more important tasks.
Attached is a patch which uses the rsync --bwlimit
option to address this problem.
This patch is ment to be applied after the lockfile
timeout patch of Bug#441459.
Note that this patch contains tabs, because the
original anonftpsync did.
