True, but I've had clojure and java apps crash with OOM in production
by giving them too little. In my experience you need to measure the
RAM consumption with maximum expected load, then add a bit for the
unexpected. Of course for a typical Gemini server that *should* be
very little. Yet I'll need to measure to know. :)

True, for a single server. But my VPS is soon running four Gemini
servers, some web ones and I have plans for more. The way JVM works it
tends to stay at max allocation, so each JVM instance is a burden.
Thankfully VPSes are huge these days. I used to have one with 64MB
RAM...

But yeah, I'll keep your project in mind. Maybe I'll find the
inspiration to hack with it on GraalVM one of these days!
