A while back we were discussing doing away with I/O to buffers, and 
accessing the data in place.  Slower access perhaps, but doing away with 
the reading and writing to/from buffers.  Haven't heard much about that 
lately.  I don't get out much.

Such type of activity would really benefit from having the capability of 
locking just the required data, and, would need the capability of 
reading and writing just the required data.

I'm aware of how useful something like SSIO would be.  I'm just appalled 
by the design and implementation.  As mentioned, it seems aimed at just 
a few current uses, and totally ignores how useful it would be for many 
more future uses.  This is rather consistent with the long time apathy 
with which VMS has been treated.  It's more a patch than an enhancement. 
  This is what I lament.
