This is completely unnecessary. Once you are using special flags to Chrome, all
expectations of 'typical' behavior are gone. You are now in an *experimental*
mode, where if someone specifies a bad token dir, if Chrome crashes, that is
fine.

Adding code bloat for checking for a condition we care so little about, is
excessive.

Very well. Deleted.
