For the last 5 years, this is the second time I am ware of this kind of issue just because of the 64KB->4KB switch on those servers, although I agree it could happen again in the future due to some new debugging features etc. I don't feel a strong need to rewrite it now though. Not sure if Catalin saw things differently. Anyway, Mike, do you agree that we could rewrite that separately in the future?
