title: Does a LibC os exist?
body: <p>I remember hearing about an embeddable OS that is essentially just libc (maybe it had support for c++). It didn't have a kernel, pipes or any of the other stuff you expect from an os. I tried looking for it <a href="http://en.wikipedia.org/wiki/List_of_operating_systems#Embedded">in wikipedia</a> but I didn't see it listed.</p>
  
  <p>Does such an OS exist? Is there an OS that supports either a terminal only or C/C++ + (tcp) sockets to communicate outside of a VM? That would be useful to me as a toy.</p>
