Got this on 12.3-RELEASE, fusefs, nginx, sendfile. Easily reproducible (just
start downloading the same big file and cancel after 1 sec, repeat 10-20
times), but my quickly writen test program which does sendfile() the same big
file info socketpair() socket - never hangs. Will try to investigate more.
