9:11:31knoboWhat is this: Unexpected error 9 on netlink descriptor 6fatal error encountered in SBCL pid 17146(tid 0x7fffe70bf700):
9:16:37|3b|supposedly that error is usually due to closing wrong FDs in another thread or something like that
9:17:54|3b|4th * in https://www.sourceware.org/ml/libc-alpha/2016-02/msg00502.html
9:19:11knobo|3b|: sounds like something that could be happening here.
9:30:03knobo|3b|: is it because close is called two times?
9:31:32knoboIf the other end calls shutdown(2), and I call close. It should be ok, right?
9:33:42|3b|calling twice sounds bad (particularly if another thread might have opened it again in between), or closing an fd that is in use by another thread
9:33:58|3b|not sure about shutdown/close, haven't done networking in a while
