digitalmars.D.learn - append - too many files

I get this error after a while (seems append doesn't close the 
file each time):
std.file.FileException std/file.d(836): history.txt: Too many 
open files

```d
auto jm_addToHistory(T...)(T args) {
	import std.conv : text;
	import std.file : append;

	auto txt = text(args);
	append("history.txt", txt);

	return txt;
}

This is a bug, please file an issue in mantis.  Phobos functions should
not leak file descriptors.

There is no error in the function or Phobos.  There may be 
another error on your system or depending on how you use it.

Could it be that more than one program tried to open the same 
file? How do you use this function?

I kinda have an update function that gets the update text, it 
writes it to the terminal, to a text file and returns the text 
(for like display on screen).

Oh, looking at my code now, I was looking at the wrong function. 
Not to do with append. Sorry, forget about it.
