Gnome::Vfs::Async incomplete?

Hello,

I am using the 2.6 version of libgnome-vfsmm right now, and I'd like to 
ask a few questions:

I am developing a Gtk+ filemanager in C++, and thus I have to implement 
asynchronous file operations like copy, move, delete and so on, in order 
to not block the GUI when the user copies files around for example. 
However, although Gnome::Vfs::Transfer seems to resemble most (or all) 
of the functionality of the C API, the Gnome::Vfs::Async namespace does 
not. It is e.g. missing an asynchronous remove function.

Is there a newer version of the library which has all the asynchronous 
functions? Or do you have an idea, how I could still solve my problem?

Thanks for your time.
