bcoca answered about why the wait\_for is taking so much CPU but  
there's another part of your question as well -- why it's taking so  
long.

If you don't specify a port or a path then ansible is just waiting for  
a set amount of time before it goes to the next task. The default  
value of timeout is 300 so should be about 5 minutes. Since you are  
checking a host that's in your inventory you probably want to check  
for the ssh port becoming active instead. Something like this:

&nbsp;&nbsp;&nbsp;&nbsp;- name: Wait for the host to accept ssh connections  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;wait\_for:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;host: "{{ inventory\_hostname }}"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;port: 22  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;delay: 20  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;timeout: 300  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;state: started

That will wait until port 22 is available on inventory\_hostname or the  
timeout of 300s (plus the delay of 20s before the first check is  
performed) has expired.
