(1) Don't use class variables (@@myfile): the value will be shared 
between all three threads, and they will stomp on each other. A local 
variable (myfile) is what you want here.

(2) Do your error handling within the thread code, so you don't need to 
mess with @@myfile to get sensible error reports outside.

Or simply set:

Thread.abort_on_exception = true

at the top of your file. This will let you see the next problem:

(3) change net::HTTP to Net::HTTP

This creates /tmp/ALP/n with a 404 error in it. This seems reasonable to 
me, since if I go to
http://table.finance.yahoo.com/table.csv?s=ALP/N
in a normal web browser, I also get a 404.

So the next thing you need to do is to work out what URLs you actually 
want to download. The command-line tool "curl" is helpful for this, and 
of course, reading the documentation for the API you're trying to use.
