I see that Zeus only claims that MRI and Rubinius are compatible. What features specifically are missing in JRuby that Zeus needs? I did not see any forking, nor C extensions, nor C ext dependencies...

Spring will soon support JRuby, after some hacking on UNIXSocket by @mrbrdo. It would be nice if other popular preloading/prebooting systems worked on JRuby too...

Oh, I just saw #297 :-(

Where is fork used? Wouldn't it be possible to just launch a new process?

Ok, I see...it's very similar to how Spring uses fork, no?

See rails/spring#449 where @mrbrdo has introduced a pooled subprocess model when fork is not available.

Unfortunately fork is pretty fundamental to what Zeus does today so JRuby support isn't planned (per #297). Sorry!
