Ok, for Interprocess internal purposes I just need 32 bit integer 
atomics (maybe 64 bit ones for 64 bit platforms), and I think every 
platform compatible with Interprocess (UNIX and Windows) will support 
them without spinlocks.

I guess the solution for interprocess would be to use a spinlock per 
atomic variable, making sizeof(T) != sizeof(atomic<T>). I'm just 
thinking about ABI issues.

Best,
