Hi,
Apologies for being unable to respond promptly. I've been traveling
(without much access) and this was the fastest I could settle down. I was
free for months and had to travel smack in the middle of the commitfest.
Incidentally I had reviewed one patch after your direct email, but as

Hi Szymon,
The commented out test that you're referring to, is an existing test (not
that I added or commented). I was going to remove but interestingly its
testing a part of code where (prima-facie) it should fail, but it passes
(probably why it was disabled in the first place)
!
So technically
OK, so I think this patch can be committed, I will change the status.
thanks,
