 Hope you've learned something useful about big locks vs. fine-grained locks!
+
+== EDIT 1
+
+Funnily enough, after some testing and playing around with the system, I've found that the big lock actually has improved
+performance significantly?
+
+Why?
+
+I think it's due to previously having a lot of spin locks, which equate to a huge amount of atomic reads/writes. Such
+operations on x86 may cause a performance problem, because they have to be synced across all cores. Having a big lock
+once on entry and big unlock on exit reduces the amount of these operations. That's just speculation, I don't have
+any real _numbers_ to back this up; it's all based on anecdotal **feel** of the system, while using it and running
+test apps.
