Right.  This is another Ruby GC issue.  If you don't call GC.start, then 
  all the documents that you have created remain open.  I assume this 
causes the OS to eventually run out of file handles, thus resulting in 
the error (which is being raised by libxml not Ruby).

By calling GC.start, the documents are freed and the file handles are 
released.

So I don't see this as a bug in the libxml bindings.
