Subject: How does ActiveRecord do it?

I know it sounds like a Rails question ... but it isn't.

Consider
irb(main):001:0> class X
irb(main):002:1>   puts "Hi"
irb(main):003:1> end
Hi
=> nil
irb(main):004:0> x = X.new
=> #<X:0x42458ac>

The "Hi" is sent to stdout as the class X is parsed.  (Well, after the
end statement.)  Right?

"Hi" is not generated when a new instance of X is created ... right?



So now consider
# in .\app\models\user.rb
class X  < ActiveRecord::Base
  puts "Hi 2"
end


"Hi 2" gets displayed by webrick every time I generate a form.

How does this happen?  Is webrick(?) reloading .\app\models\user.rb every
time a form is generated?



(And now a Rails question ...)

Assuming it is reloading .\app\models\user.rb in development mode ...
will it do this in production mode?
