Probably from getuid() returning that. You tell me whether it's possible for 
the syscall to return UINT_MAX on Dragonfly -- on Linux, it isn't, since 
ULONG_MAX-4095..ULONG_MAX are reserved for error codes.

The system daemon will allow any UID to be passed there, provided it exists in 
/etc/passwd.
