It's a race, so a testcase is always going to be a bit hit-and-miss. 
But something similar to the example from the original bug report would
probably show it up fairly reliably.  I'll see what I can do.

I did include a changelog entry when I resent the patch this afternoon
though you're right that I forgot it earlier.

I think I also ought to run the testcase under valgrind for a while to
convince myself a bit more thoroughly that it's OK.

Thanks
