Eh? Chris Wright's original rlimits patch was very straightforward
(unlike some of the other rlimit-like patches that followed).
I haven't heard the downsides of it yet.

simple rlimits:
logical extension of standard, flexible interface
fine-grained per-process access to nice levels and priorities
managed with standard tools
fairly broad possible applications
clean enough to be added unconditionally
already doing mlock this way!

new, narrow magic group interface (module parameters!)
boolean granularity of access to all RT levels and maybe mlock
potential interesting interaction with other LSMs
not orthogonal to mlock
not appropriate for every box out there
requires lsm and (sysfs or modprobe)

Mathematics is the supreme nostalgia of our time.
