Oh, and before people start telling me that RCU was successfully used in
AIX/projectX/xxxx/etc, you have to realize that I don't give a rats *ss
about the fact that there are OS's out there that are "more scalable".

The last time I looked, Solaris and AIX and all the rest of the "scalable"
systems were absolute pigs on smaller hardware, and the "scalability" in
them often translates into "we scale linearly to many CPU's by being
really bad even on one".
