st: Run time for 3-level model in xtmixed

Hi all,
I am trying to estimate a somewhat complicated 3-level model that
includes cross-level interactions. I'm also estimating it over 20
imputed datasets. It's been 24 hours since I hit return and still no
results. Is it possible that this is normal? I'm running the model
on a 2012 Macbook Pro.
The data structure is 3 waves of observations, nested in ~2700
children, who are then nested in ~200 neighborhoods.
Here's the syntax:
mi estimate: xtmixed wratraw c.conaff90##cohort##time ///
|| nc: time, covariance(unstructured) ///
||subid: time, covariance(unstructured) mle
Thanks,
-Bill
