A simple configurable hog program to simulate apps that exceed their memory allocation.

Configuration

• HOG_MAX_BYTES: How much memory to hog before exiting. Default is LONG_MAX, which essentially means no limit. Set to e.g. 2147483648 to hog up to 2 GiB.
• HOG_WAIT_SECONDS: How long to wait before we start hogging. Default is 0, which means don't wait at all. Set to e.g. 2 to wait 2 seconds before the hogging begins.
• HOG_GOAL_SECONDS: how long should the allocation of HOG_MAX_BYTES happen over? Default is 0, which means hog as fast as possible. Set to e.g. 60 for the hogging to happen over a minute.
• HOG_CHECKPOINTS: how often should the hog stop and sleep in order to hit HOG_GOAL_SECONDS? The higher this number, the more accurate the stopping point (and the more likely the hog is to stop if it receives SIGTERM). Default is 64.
