The hack isn't a complete solution - it merely lowers the performance
hit to some degree by removing disk I/O. There is still considerable CPU 
usage in xenstored simply by copying data to/from tmpfs RAM disk. In my tests
using tmpfs reduces CPU usage from 60% to 30%. The real fix in XenD
ought to reduce xenstored CPU usage to < 1 %
