Rails - Sep 2008 - make a system call and proceed without waiting for result?

This is probably a general ruby question:  in one of my models i need to
make loads (up to 600 or so) of system calls with the curl command.
It''s a fire-and-forget kind of deal - i don''t care, at that
particular
moment, whether the calls were successful or not and i certainly don''t
want to keep the user waiting for the html responses to come back.

Is it possible, with a call to ''system'' (or some other method)
to carry
on without waiting for the results?

Even simpler. Use ruby ''fork'' method. Example:

#show time now
puts Time.now
fork do
  #long running process
`sleep 20;curl -O www.somesite.com/bigfile.tgz`
end
#this time is nearly same as when we started, no delay
puts Time.now
