No, this isn't implemented so far. Looking into the sources only NQUERY
mode makes use of MAPSHAPE/IMAGESHAPE for queries.

The default for featureNquery is to use the current map extend to
determine all features of the slayer to be used for the query. This
obviously can take a long time and I can imagine that this results in
some internal problems ... 

If possible using a determined admin boundary instead of a double
feature query should do it.

Regards,
