Kernel mods and RTIngres

Bogus!  Other vendors seem to be able to design software to cope
with a variety of systems without asking one to modify his kernel.
For example, one can write per-system-type user-mode "lock"
interface modules that work acceptably well.

Not only that, but when RTI made our Ingres users install their
lock driver, it turned out that their software still didn't
support concurrent database updates!  What was the point of the
lock driver??
