[undertow-dev] Undertow and non-blocking File IO

I just started playing with Undertow, but I had a couple of questions about the use of non-blocking operations vs using the worker thread pool. In the ResourceHandler.java <https://github.com/undertow-io/undertow/blob/master/core/src/main/java/io... it appears to dispatch itself onto a worker thread, and then uses blocking file IO to actually read the file. I'm curious why a AsynchronousFileChannel <https://docs.oracle.com/javase/7/docs/api/java/nio/channels/AsynchronousF... wasn't used to read from the file in a non-blocking way? This would be in keeping with the non-blocking IO threads. I wrote a quick HttpHandler that used the AsynchronousFileChannel <https://docs.oracle.com/javase/7/docs/api/java/nio/channels/AsynchronousF... and it worked really well. However, when creating AsynchronousFileChannel <https://docs.oracle.com/javase/7/docs/api/java/nio/channels/AsynchronousF... you have to specify the ExecutorService to be used to schedule the completion handler callback on. I was able to use exchange.getIoThread().getWorker(), but I'm curious if there is a way to schedule it back on the IO Threads? It just seems "purer" keeping everything on a single IO thread per core. thanks Andrew
