Maybe one can try setting the read and write threshold to the same.
The select high cpu issues didn't seem to kick in for values > 4064 when
the read threshold and write threshold were set the same > 4064. eg even
4096!

A few sleep commands in the loop are also not a bad idea either.
In either case, we've had a very cursory attempt at:
