Looks like pthreads aren't working properly:

"
  ./test-int-array-jack 512
starting ringbuffer stress test (2 minutes max)
buffer size (bytes): 512
array size (bytes): 256
reader started on cpu 14631
"

The writer is never started. Or perhaps
printf is not working, but probably not, since
it's been like that for several minutes.


Same with
./test-int-array-portaudio-nobarrier 512


Also note that the programs were compiled with Sun's C compiler, not gcc,
since gcc doesn't seem to be installed on the machine.

I'm no Sun expert, so I don't know what may cause this.
