I am looking for a *quick* test method just looking at the stream and deciding
in about 5 seconds weather there is a freeze or not. The test is supposed to be
run by cron at regular intervals and if a freeze is found it will send me an
alert email.
The URL it uses is in a disk file and is read from the file like the download
script does. This is designed so I can easily modify the URL if it changes even
when there are scheduled download jobs not yet executing.
(I use at scheduling for the downloads)
