Comment:

 The above commit was incorrect and was ultimately reverted.

 The idea was merged again in 91c6b1f54aea658b0056caec45655475897f1972,
 which does not exhibit this regression. I'm not entirely sure why this is
 the case, although I suspect the phenomenon was due to sloppy test
 conditions on my part as I have been unable to reproduce the issue.
 Closing.
