comment out isnan()

Browse source 
It conflicts with Jester's debugging setup, and Andy says there should be
no NaN in the first place. This is a bug that needs to get fixed. Just
enable isnan() if you want to detect NaNs in the meantime. (The MP system
creates them ATM. The property getters shall turn them into nil.)
