I try understand how redis support should work.

In the contrib web2py code I see function RConn() with code inside:
 

> instance_name = 'redis_conn_' + current.request.application

if not hasattr(RConn, instance_name):

    setattr(RConn, instance_name, StrictRedis(*args, **vars))


It looks like this should separate (isolate) redis/StrictRedis instances by 
request.application.

However, if I create 2 redis/StrictRedis instances and save them as 2 
different variables,
they will share same data.
To really separate them, I need set different db=NNN parameter:

r1 = StrictRedis()
r2 = StrictRedis()
will be same,

but
r1 = StrictRedis(db=1)
r2 = StrictRedis(db=2)
will be different.

So, is the per application isolation really working?
