It isn't fragile, it is very robust. Chris' statement (to my mind) means 
either that it is an additional layer of complexity to your programme 
(which you need to debug) or the pervasive fear of threaded programming, 
which has its pitfalls but is very rewarding and not hard to do safely 
and easily unless you do something agressive and complex.
