I am no expert, but loops seem to me very hard to parallelize.
The very idea behind a loop is that the second itteration
happens after the first itteration, the third itteration 
happens after the second itteration, etc. Many applications
of loops would break if that were not the case. I can see
why this would not be an issue with a simulation, but how
is Stata/Mata supposed to know? 

Hope this helps,
Maarten
