I myself have had headaches about this problem (unsafe DLCP) too.  Indeed, I do 
not have problems with DLCP, since I have access only to IA-32 platforms, but I 
really like to make my code more portable.

Currently there is no known way to make memory barriers portable.  So I guess 
it might be a good idea that GCC provide built-in functions to do the job.  On 
IA-32 platforms it is a just a null operation, but on other systems it might 
really do significant stuff.
