Detailed Description

Assert close called on open filedescriptor.

...
scoped_ptr<Fd> fd; // calls close when going out of scope
try {
  fd.reset( new Fd( "/some/file" ) );
} catch ( ... ) {
  // open failed.
}
read( fd->fd(), ... ),

Todo:

It's dumb. Openflags and more related functions (read/write..) could be added.
