Ok, you're trying to delete the file from the same process?

If the file was created with this syntax:

f = File.open('foo', 'w')

then you need to close it (f.close)

sometimes that doesn't work, so better if you do the file operations
in a block:

File.open('foo', 'w') do |f|
  f.puts "xxx"
end

That will release the file description and let you unlink it.

If, by contrary, you fold the file descriptor, nothing can be done
(use Unlocker to see who is holding the file).
