i'll look into this one ...

1. jack overrides the -audiobuf settings
2. override takes ms as argument, not samples
3. sleepgrain takes ms as argument. it should be in the range of 0.1 to
   5. 0.1 produces a lot of overhead, though.
for jack, don't touch the audiobuf setting at all, the sleepgrain for
128 samples will be automatically set to 0.66 ms (48000 kHz)

i'm using:
./configure --enable-newhash --enable-jack --enable-fftw --enable-simd
--enable-optimize=pentium4 --enable-threadedsf --enable-atomic

note: --enable-optimize takes an argument
      after having several problems with icc, i'm not using it any more
      (might work now, but not sure)
