RE: [reSIProcate] 'this' : used in base member initializer list
I've checked and Derek is right - we are only just storing the 'this'
pointer, which should be safe. I've added a #pragma that disables the
warning on VS.NET compilers.
Thanks,
Scott

AFAIK, this is a safe use of the this pointer; the value is being stored,
that's it. I don't think other(smarter) compilers will even complain, but I
haven't checked.
