A few things:

1. I can't reproduce what you're describing. I get the same person object for all three lines in the example (adding a 'p' to the last line). Not sure why that would be.

2. around(:all) is not supported (needs a better error message), but before(:all) should work.

3. What you're trying to do is a bit unusual. By default, each example is run in a transaction which is rolled back at the end of the example. This keeps all of the examples isolated from each other, which is a very desirable outcome.  If you use before(:all), the created object will remain in the database, so it's up to you to clean it up yourself instead of relying on ActiveRecord to do it for you.

Also, before(:all) (or before(:each)) in the configure block in spec_helper adds that to every example group. i.e. it's the same as declaring that block in each group. If you're looking to do this once per run, use before(:suite).
