[pymvpa] hang on poly_detrend

I've been using poly_detrend on a range of datasets and classification 
tasks recently, with success. But on my latest script it hangs, and 
never completes (the step that usually takes ~1s on a dataset of ~500 
cases by ~1000 features, didn't complete after several hours). This only 
happens with a very particular set of parameters (certain datasets, and 
dimensionalities). Any suggestions why, or how to proceed in tracking 
the problem down?
