We have to see the parameters passed to poll() (perhaps from strace, perhaps
from a backtrace on a debug build, perhaps from somebody understanding the
assembly code with the same build you got the backtraces from).

The timeout is hard-coded to 2 seconds, so it isn't supposed to block longer
than that.
A FIN has already been sent on the connection, so poll() could wake up on
socket activity before "too long."

If server-status is enabled, a thread with this backtrace should show up as "C"
(closing).
