I use the following patch: (against the xen-1.1 tar.gz)
diff -pru ../../xeno-1.1.bk/xen/common/domain.c xen/common/domain.c

This will result in a $40000001 count and then after a switch to another
table and an unpin of the initial table, the count will be 0.

yes, xen-1.1 was the latest version available outside of bitkeeper.

yes, except that I don't want to deal with the bitkeeper licence and figure
out whether I'm allowed to use it or not.
