sendfile() does not return on partial write and tries to push more
until error. On fast link it most likely succeeds, so that it is unkillable
even with SIGKILL.

I do not think so. It is rather scheduling breaker. If connection
is idle 99% of time, but wakes each sndtimeo-1usec, it must yuild,
otherwise thread is lost for production.
