The linuxulator is synced on amd64 with i386 (since a while). This means TLS is working now and we have the same (a little bit buggy) futexes.
Roman is slowly working on the *at() commands. He also applied for the GSoC this year again. Kib is willing to mentor (in case Roman gets a free seat in the SoC). I rejected the mentoring position this time, as I don’t know if I will have enough time this summer, but I hope I will be around.
