Some explanation of the test program.
./schedulerissue 1 4096 8 2000 1 producer and 1 consumer buffer size of 4096 doubles * 8byte 8 buffer (256kB total buffer) 2000 messages
./schedulerissue 2 4096 8 2000 2 producer and 2 consumer buffer size of 4096 doubles * 8byte 8 buffer (256kB total buffer) 2000 messages
It was not 512KB bytes in the test before, but 4MB. But there is the same problem with a total buffer size of 48kB and 4 threads (./schedulerissue 2 2048 3 20000).
