Uncommit delay option

Hi,

I'm still looking for the perfect garbage collector. Went with G1 for a
long time - and happily. Then ZGC was tried, but Linux's problems with
correctly reporting multi-mapped memory are a real problem. Thus now
Shenandoah!

My question regards this article:
https://shipilev.net/jvm/anatomy-quarks/21-heap-uncommit/ from the
absolutely excellent JVM Anatomy Quarks series (best JVM coder pr0n I have
read in a long time).

The article talks about uncommitting memory after 5 seconds. I want to try
that, but can't find the option for it. I'm using JDK 13. I ship to end
users, so keeping memory use compact is essential.

Many greetings,
Stefan
