IoT.js unexpectedly exits (caused by SIGPIPE) when the active socket is closed by the client

[Erko Püi]

build:

./tools/build.py --jerry-heaplimit=2048 --jerry-profile=es2015-subset

Test code:
test.js

var fs = require("fs")
var http = require("http")
var port = 8888

http.createServer(function(request, response) {
        console.log("Request for path: " + request.url)

        fs.createReadStream("/tmp/100M.bin").pipe(response)
})
.listen(port, function() {
        console.log('HTTP server listening on port: ' + port)
})

#prepeare the file

dd if=/dev/urandom of=/tmp/100M.bin bs=1M count=100

#on the server-side

gdb iotjs/build/x86_64-linux/debug/bin/iotjs
run test.js

#on the client-side

wget -O - localhost:8888 | pv -L 10k > /dev/null
#after a few second, press ctrl + c (close connection)

#GDB result:

Possible solution somewhere in main thread:

  sigset_t set;
  sigemptyset(&set);
  sigaddset(&set, SIGPIPE);
  pthread_sigmask(SIG_BLOCK, &set, NULL);
