Here's what I get on a my UP 5.3-STABLE with ULE and PREEMPTION (thr & lc_r 
not installed, hence not tested):

[lofi_at_kiste]:~ > time ./aqueue_linuxthreads -n 10000000
pusher started
poper started

real    0m19.157s
user    0m4.639s
sys     0m5.545s
[lofi_at_kiste]:~ > time ./aqueue_kse -n 10000000
pusher started
poper started

real    0m32.619s
user    0m31.858s
sys     0m0.532s

Still slower, but already lower than factor 2.
