[Qgis-developer] disjoint checking in geometry addPart

I am wondering if this is correct to check if polygons are disjoint when 
trying to add a new part to a multipolygon.

Indeed if you try add a new part having a segment in common with an 
existing part it won't be ok.

Also, while trying to slit parts, I cannot use addPart method as it is, 
because the parts are not disjoint.

What do you think?
Should we rather use GEOSOverlaps ?

Thanks a lot
