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.
