[chef] Prevent LWRP from notifying?

[< >]

Currently I am using the python cookbook (authored by opscode).  When
installing a pip with it, it always sends a notification even if it noops
because the pip is installed already.  I was wondering if it is possible for 
an
LWRP to not send a notification when it NOOPS.

I dug into the resource code a bit and I noticed that most full fledged
providers (like the template resource) use updated_by_last_action.  Is this
what causes the notifications or not? 

Any input would be lovely as there are a bunch of processes I'd love to 
restart
only after a pip has been installed.
