You can use fibers in C++ if you find a library to do it

The java approach is Netty and NIO.
Netty and NIO are an event dispatching mechanism (think
libebevent) backed by a ForkJoinPool. No fibers there. Java
/does/ have fibers in Quasar, though the implementation is a bit
weird because the Java instruction set doesn't support
continuations.
Message passing via std.concurrency is important to note. The
scheduler is pluggable and can seamlessly multiplex fibers on top
of a thread pool (the Erlang "millions of threads" approach).
Thread local by default is notable as well, though fibers throw a
wrench in this. The "synchronized" keyword is inadvisable in
modern concurrent programming. I think it remains largely to ease
porting code from Java.
