Database software for UNIX systems

[Mats Wichmann]

The version of Ingres I have seen depended on existing locking
routines if they were there (as they are in many microports),
but in this case you had to modify the process exit code (inside
the kernel, not the stub in libc) to make sure to leave things clean.
The other approach, of course, is the already mentioned
"device driver". Either way, this is not very nice.
