The issues of a single GIL haven't gone away. The only difference is that the
GIL is (probably) released much more frequently than it was before. The
changes are to do with correctness (specifically deadlock avoidance) rather
I don't know what the performance effect would be on a multi-processor. Matt
said that he could run more threads but I don't know what hardware he has. I
noticed a (small) degradation on my uni-processor - as would be expected.
