Comment (by duncan):

 Thanks Simon!

 To answer your Q, linear algebra :-)

 To be clear: this isn't critical for my application, but I can see how
 people following a pure parallelism strategy would hit this and it'd be
 jolly confusing. I've now got a different solution using explicit IO
 threads. Less elegant but works well.
