[Samba] Samba4 additional DC - few questions

Hello to all

I've been testing Samba4 for a while and noticed non critical issues so far.
My plan would be to use one samba4 DC as additional DC in win2008 network

So I do have 4 win DCs in 4 separated sites (one domain and 4 sites)
and I want to use this Samba4 as DC in 5th separate site .
It will be acting  only as AD DC , Fileserver and print server.

Since I noticed (from the forum) that Filesharing is kind a more stable 
in Samba3 than 4 ,   I decided to use Freenas as Fileserver (joined to 
the domain, and using samba4 as domain dns )
and I must say the cooperation between S4 and FreeNas  (in my test-lab) 
(just joined to domain without using freenas-samba4) is pretty stable (I 
virtualized Samba4-Centos and Freenas9 on the same "metal")

There is only one issue I noticed regarding replication (in my lab 
also): If I turn off replication beetween DC in AD sites-and-services 
console , the Samba4DC and WINDC are still replicating . How come ?

The main question would be :
If I join Samba4 DC in this productional Win2008 Domain (4 sites) , is 
there any chance that this Samba4 DC endangers the WIN domain ?
If Samba4 site,for some reason,  does not work , it is acceptable 
because this is not critical site and I always have time to fix it somehow.
But if potential problem in Samba4DC causes problem in WIN-part of the 
domain (fsmo goes down because of some false replication or something 
like that)
than it would mean high risk for me

So does joining Samba4DC in windomain represents any kind of danger or not ?

I really appreciate, and congratulate on,  Samba4 work and hopefully 
replace very big part of windows portion of customers intranet

Thank you very much in advance
