1 thread per connection??? Not doing continual GC in a separate thread and instead taking 7 seconds and blocking everything?

What is this the 1990s?

Feel free to fork MzScheme and replace the garbage collector with a new one that runs continuously.

Surely there's a way to target the JVM?

I'd trust my life on the JVM, it's pretty battle tested, and the GC is simply awesome.

You sure you want to do that? :-)

Yeah I'd trust my life on it. I've had java processes running for several months without issue. The hardware fails before the jvm does.

I wouldn't trust anything from microsoft though.

I've helped build rail control systems that run on Java, so you're probably trusting your life to Java daily without knowing it.
