* call-seq:

* Process.setrlimit(resource, cur_limit) => nil
*
* Sets the resource limit of the process.
* _cur_limit_ means current (soft) limit and
* _max_limit_ means maximum (hard) limit.
*
* _resource_ indicates the kind of resource to limit.
* Although the list of resources are OS dependent,
* SUSv3 defines following resources.
* If _max_limit_ is not given, _cur_limit_ is used.

* [Process::RLIMIT_CORE] core size (bytes)
* [Process::RLIMIT_CPU] CPU time (seconds)
* [Process::RLIMIT_DATA] data segment (bytes)
* [Process::RLIMIT_FSIZE] file size (bytes)
* [Process::RLIMIT_NOFILE] file descriptors (number)
* [Process::RLIMIT_STACK] stack size (bytes)
* [Process::RLIMIT_AS] total available memory (bytes)
