I remember running this (way earlier than 2011, like 2003?) and it was really cool but it’d slow down the real time clock on the ‘host’ (co-habitating?) Windows install. I figured that was due to the clock being tied to cpu cycles and Linux stealing some of those. I’m not so sure about that explanation anymore, but I don’t have a better hypothesis either. Funny how that little detail stuck with me for almost 20 years…
I thought it was due to the timer's frequency being programmable, and both operating systems setting and assuming different values. It's been a long time though and my memory is fuzzy.
