/* this file serves the same purpose as thr_bufs2.h in the threaded version

   Unlike thr_bufs2.h, which has two separate lists of buffers,
   reader_buf[] and worker_buf[], so that the threads can be asynchronous.

   pcomp workers are asynchonous as well, but, initially, there is an
   array that has an entry for each worker (worker_buf[]), and a queue
   that captures which buffers are ready (work_q[]).
