On M1, Acme win fails with "cannot find self in altdequeue" from libthread #468

If I run win in an Acme tag, it opens a window, but it stays empty and this appears in +Error:

win: qlock pc=0x100fe9090 owner=14cf05de0 self=14cf04420 oops
cannot find self in altdequeue
win: exit signal: sys: abort

I'm running macOS 11.1 on an M1 laptop:

One of the intervening commits fixed it. Thanks, @rsc (probably)!
