No luck replicating power issues here. I'm using this code:

var wifi;

function onInit() {
  wifi = require("EspruinoWiFi");
  wifi.connect(WIFI_NAME, { password : WIFI_KEY }, function(err) {
    if (err) {
      console.log("Connection error: "+err);
      return;
    }
    console.log("Connected!");
    wifi.getIP(function(err,ip) {
      console.log("IP address is http://"+ip.ip);
      createServer();
    });
  });
}

function createServer() {
  var http = require("http");
  http.createServer(pageHandler).listen(80);
}

var fileNo = 0;

function pageHandler(req, res) {
  var d = "";
  var boundary;
  req.on('close', function() { 
    console.log("File uploaded");
  });
  req.on('data', function(data) { 
    console.log("Got "+data.length+" bytes");
  });
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('<html><body><form method="post" enctype="multipart/form-data">');
  res.write('<input type="file" name="file1" id="file"><input type="submit">');
  res.end('</form></body></html>');
}

and uploading a big file. The voltage is rock solid at 3.32v

Having said that, I could reproduce your out of memory issues at least - and hopefully I found something that'll fix them. It seemed to be related to what happens when we're trying to send data to a socket at the same time as ESP8266 is sending it out.

If you upload now the out of memory issues should be gone (or at the very least, better).
