yes, for sure, the problem is that you need to integrate the whole jvm
part with the nginx event loop, you cannot use other ways (unless you
introduce back threads)

This is what i told you in the clojure list: invest on implementing the
nginx api as jni, otherwise all will remain a proof of concept.

Just as an example, how do you plan to integrate with mysql in a
non-blocking way ? you need a mysql adapter that will use the nginx api
and so on... (huge work honestly)

and yes, until you do not manage to integrate the nginx api in jni, the
jvm is a blocking part for nginx :)

I hate to bore you expecially because you are pushing a new technology and
the last thing you need is losing entusiasm or being blasted, but the
world is already full of people doing non-blocking programming in the
wrong way :)
