OK, happened again, so icecast output goes down, liq stops outputting on
stdout, doesn't respond to ^C. server socket is still connected (no timeout),
and tells:
```
uptime

END
request.alive

request.on_air

END
request.trace 7

du chien.mp3";...].
[2018/08/17 01:07:13] Currently on air.
END
cross.status

END
```
But then I hit ^D and couldn't talk to liq through the socket anymore.
The on air metadata is on sync with the last log:

This happened at 01:07:13, stream started at 20:58:25. Liq process was still
using RAM and CPU, strace yields this:
```
strace: Process 29247 attached
rt_sigtimedwait([INT TERM],
```
I couldn't get a coredump as the env wasn't set for it, but I restarted it
using gdb, so we'll see...
ocamlc is: 4.05.0
liquidsoap is 1.3.3 from opam
OS is Ubuntu 18.04 64 bits
I will try the branch if that is relevant.
The liq code is here :
https://gist.github.com/gilou/33ffcdb2d345ea1f09642b4399f33f84
This script (though more complex) runs on liq 1.2.0 / 4.02.3 / ubuntu 16.04.2
compiled from the source tarball without failing.
