This library depends on gntdev for the client and gntalloc for the server;
these were merged in 2.6.39. The client can be used with 2.6.32.x kernels
however it is not possible to detect when a peer crashes or exits without
calling libxenvchan_close() on that kernel.

This library does not require that either peer is dom0; it can be used for
both domU-domU and domU-dom0 communication.

The latest version of the patch can be found in the xen-devel archives.
