Problems with the process hierarchy with volatility 

Volatility has problemas with the hierarchy of smss.exe:

**Session 0**
smss.exe
> smss.exe (This process does not usually exist because it dies)
>> csrss.exe 
>> winint 

**Session 1**
smss.exe
> smss.exe (This process does not usually exist because it dies)
>> winlogon
>> csrrss.exe
