This means the environment is growing with each iteration. Most UNIXes impose a limit on the total size of the environment [1]. Once the limit is reached any attempt to execute a program will fail with E2BIG error, visible via strace. With the infinite loop this leads to a zombie process that consumes a lot of CPU.
