the ticket was filed mid-Dec. 2014 and stated that all threads leaked memory when closed. I think there was an earnest misunderstanding, since the ticket was still open when i read it, but has clearly been fixed on linux/OS X.

And i couldn't find the ticket when i looked, after the user deleted his comments. So it seemed a bit like a direct attack on the language's fitness for developemnt, but also like a misunderstanding.
