Sorry, misdiagnosed that one. It is rather more obscure:

If logPath is on a local disk, NSLog and output directed to stderr 
appear in logPath.

However if logPath is inside an NFS-mounted home directory, only stder 
output appears, but NSLog output goes missing. When exactly the 
freopen happens doesn't matter.
