update on unix(4)

  Hi,

I'm aware of 3 recently discovered regressions due to my d15792780760:

1) sway gets into infinite loop, bug 286692.
2) A panic reported by Alexander on recv(2).
3) A panic found by syzkaller on shutdown(2).

The 1) is probably top priority since happens all the time and blocks certain
desktops setups.  The 2) seems to happened only once, not very clear from the
email. Alexander, can you please confirm? The 3) should not happen with normal
applications.

I'm writing this email cause I'm going almost offline for a week. There is
small chance that I will have a good internet access to work on them.  Please
don't perceive no progress on the problems or no response on emails as being
abandoned. I'll be back next Tuesday and will focus on them. Very sorry for
such bad scheduling.  I planned that between May 5 and today there is enough
time to discover and fix possible regressions, but was wrong.
