FUSE filesystems are not PUFFS servers, they do not have access to
PUFFS-supplied uucred. perfused is the PUFFS server. It has the data, 
but in order to pass it to the FUSE filesystem, the FUSE protocol 
neds to be extended. As I explained in another post, I have not been
able to get consensus from FUSE maintainers on this extension. Therefore
I have to fallback to asynchronous fecth of secondary groups through 
a system call.
