在phantomjs上,为什么没有呼叫连接

我正在尝试在以下简单脚本(称为te.js)上运行phantomjs并在其上使用ubuntu 12.04上的“strace”:

$ strace -o tmp.txt -e poll,select,connect,recv,sendto,recvfrom ./bin/phantomjs --disk-cache false te.js

以下是javascript脚本:

var page = require('webpage').create();
var system = require('system');

page.onConsoleMessage = function(msg) {
    system.stderr.writeLine('console: ' + msg);
};

page.open('http://st.pimg.net/tucs/img/cpan_banner.png', function() {
    console.log("got image\n");
});

这是strace写给tmp.txt

的内容
poll([{fd=7, events=POLLIN}], 1, 10)    = 1 ([{fd=7, revents=POLLIN}])
select(4, [3], [], [], {0, 0})          = 1 (in [3], left {0, 0})
select(4, [3], [], [], {0, 0})          = 1 (in [3], left {0, 0})
select(4, [3], [], [], NULL)            = 1 (in [3])
select(4, [3], [], [], {0, 0})          = 1 (in [3], left {0, 0})
select(4, [3], [], [], NULL)            = ? ERESTARTNOHAND (To be restarted)
--- SIGINT (Interrupt) @ 0 (0) ---
+++ killed by SIGINT +++

我原本打算看到“连接”的电话,但我没有。想知道为什么。

顺便说一句,我使用了wireshark,它表明phantomjs确实尝试建立与HTTP服务器的连接。
