Bug#1099191: debian-installer: scanning the mirror stalls frequently

[Kentaro HAYASHI <kenhys@xdump.org>]

Hi,

Surely it might be region specific or temporary issue.

According to
Debian mirror status [1], mirrors.xtom.jp was timed-out
at that time, but it was resolved now.

I've tried again and this issue is still reproducible even though mirror
status was resolved.

[1] https://mirror-master.debian.org/status/mirror-status.html

I've collected syslog.
If the problem was reproduced, it takes 20 or 30 minites to be
processed.
It seems that choose-mirror causes this edge case.

Case 1:
