Technically, no identifiers should ever begin with a '__' prefix.  This 
prefix is reserved for any use by the C standard (section 7.1.3) and is 
commonly used to generate temporaries by compilers.
Xen does use '__' frequently as a prefix.  I'm not sure it's worth 
removing.  It's probably best to avoid doing this in new code though.
