Bug in statistics(runtime) on Windows XP?

[Robert Virding]

I am running Erlang R11B-0, the pre-compiled distribution, on Windows
XP. The figures I get doing erlang:statistics(runtime) are completely
weird, they seem to have no relation with what the OS reports and what I
expect. They are at about 1/8th of wall-clock time on an otherwise
unloaded system. Is this a bug, or does runtime mean something different 
here, or what?
