When the Kubernetes, OpenShift or OpenShiftPods drivers start a
container, they replace the image entrypoint by a busy loop:
/bin/sh -c 'while true; do sleep 30; done;'
The argument to sleep is parsed as a floating point number via
strtold(3) which states:
An infinity is either "INF" or "INFINITY", disregarding case.
Remove the `while true` and sleep for eternity instead.
