nacl_io fopen fails after fwrite

[John Freeman]

I am mounting the HTML5 filesystem with the following:

mount("", "/persistent", "html5fs", 0, "type=PERSISTENT,expected_size=1048576");

I create a file using the following

FILE *logfile = fopen("logfile.log", "a");

fwrite("test", 1, 4, logfile);

fclose(logfile);

I can call the above code multiple times without any problem.

After executing the above code, the following code will fail

FILE *logfile = fopen("logfile2.log", "a");
if (logfile == NULL) {
  // fails here
}

I can reproduce this with the nacl_io_demo code

These steps always fail

1. create file

2. write to file

3. close file

4. create file 2 // fail

The following steps never fail

1. create file

2. close file

3. create file 2 

4. close file

5. create file 3

6. close file 3
