The epoll mode definitely exists in spark, but the official
documentation does not mention it, nor any of the other settings that
appear to be unofficially documented in:

I don't seem to have any particular performance problems with the
default NIO impl, but the "lower gc pressure" mentioned in the
official netty docs does seem

However, the fact that it's not even documented gives me pause. Is it
deprecated, or perhaps just not useful? Do I have to stick the native
library jar into the spark classpath to use it?
