I thought about that too.  I think technically param.c is meant to have
the changable parameters, and sysv_sem.c should just use what is in
seminfo and not look at predefined constants.

This gets back to the "do we want a somehow modified seminfo" to work
(with "gdb --write" or a newly introduced system call or possibly a
superuser-only semctl command)?
