esp32 E.openFile stops working after multiple fs.readFile and fs.writeFile

First off, thank you to everyone who has contributed to the espruino project, I love it.

I'm running into an issue using an esp32 where, after multiple calls to fs.readFile / fs.writeFile, E.openFile starts returning undefined, and both fs.readFile / fs.writeFile start returning false. Below is an example of fs.writeFile returning false after only 10 writes:

E.srand(4546455454545454);


var fs = require('fs');

function writeData(i){
  if(i < 100){
   var data = Math.random().toString();
   var name = `file_${i}`;
   var res = fs.writeFile(name, data);
   if(res){
     console.log(`wrote... ${name}, ${data}`);
     setTimeout(function(){
       writeData(i + 1);
     }, 100);
   }
   else{
     console.log(`did not write!, ${name}, ${data}`);
   }
  }
}

writeData(0);

I don't think there are any js functions exposed to inspect the situation that is causing this, but please let me know if there is. Also, I'm using a setTimeout above so I don't hit the watchdog timeout, basically simulating if I typed this into the espruino IDE 9 times. below is version information:

Also, I've tried variations of this with E.openFile thinking that I could circumvent the issue but the same problem occurs.

Thank you in advanced for the help!!
