³currentPath² property in doc gets set once. Observation gets dinged about
200 times. Removing the ³reloadData² didn¹t affect this. Same observer in
another file gets dinged once, like it should. Stack trace always leads
back to where "currentPath" is set in doc. Any theories on what could cause
this observer to have diarrhea?
