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.

Do you ever question the choice of MzScheme?

It had to be some dialect of Lisp with continuations, which meant Scheme, and MzScheme seemed the best. Our first version ran on Scheme48, but that was such a pain that we switched.
