Which makes me wonder if anyone has seen any realistic workload type under
which kse library would outperform libthr ?
My experiences have always been pretty much the same as yours - everything
seems to be faster with libthr and in the case of mysql, even more stable.
So shouldn't libthr be made the default one instead of libkse ?
