implementing posix_setrlimit

Hello- We are planning on implementing posix_setrlimit() as a sister function to posix_getrlimit() to: a) protect against runaway/buggy programs from bringing the server down and b) to allow a program that genuinely requires a lot of CPU time and/or memory to ask for it (by modifying its soft limit all the way up to an administrator-imposed hard limit) Is there any particular reason than this has not already been implemented, and if not, would it be a valid contribution to the PHP language?
