newbie problem with nothrow

[WhatMeWorry via Digitalmars-d-learn]

Is there a way to turn off nothrow or work around it? Because to 
me it looks like nothrow prevents me from doing anything useful.

extern(C) void onKeyEvent(GLFWwindow* window, int key, int 
scancode, int action, int modifier) nothrow
{
     if(queue.roomInQueue())
     {
         auto event = new Event;
         event.type = EventType.keyboard;
         event.keyboard.key = cast(Key) key;

         // etc.
}

Error: function 'event_handler.CircularQueue.roomInQueue' is not 
nothrow
Error: function 'event_handler.onKeyEvent' is nothrow yet may 
throw


The compiler wouldn't let me just remove "nothrow" from the 
function. I tried a kludge where I had this function just pass 
all its parameters to another throwable function, but this caused 
errors as well.

So I'm stuck.  Anyone know how to proceed.
Thanks.
