I don't think it's possible - although you could always load that 
kernel settings file.
Anyway, I think of having an additional open mode to have uncached file 
access - it's already there for BSD, so we could just copy their flag 
It's already part of fcntl.h in the repository, and maybe we will 
implement it already in R1.
