Make a system call and proceed without waiting for result?

Rails

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
