Re: ANNOUNCE: secure identd v0.3

rlimits can be used as a safety net, but I prefer that the program
itself remains in control of its resource usage. I just don't find
it very elegant to crash and die on illegal input...

For example, when all data objects have limited size, and when the
number of objects instances is limited, so is the amount of memory
required to hold those objects.

This just changes some programs into special-purpose cache managers.

In the days of 16-bit and smaller computers, real programmers had
to do real work to make their programs actually fit the machine.
Perhaps I am just showing my age.
