"And, the worst problem I faced was of sockets. Non-blocking, multi-plexed and cross-platform socket support with C is basically non-existent (unless I wanted to use libev or libevent,"
What are you talking about? Most every single evented io library out there just boils down to a single system call in the underlying language - C: epoll(or select, poll, or kqueue) on socket/file descriptors. You do know that socket() returns a socket, which is actually just a file descriptor, right? You don't need libev and libevent because you can just write your own in two seconds with epoll! And if you're really attached to having the library handle the work for you you can always use one of the many cross-platform event libraries, like Glib which, last I checked, works on Win32, Mac, and Linux.
