No. Even if it were technically possible to implement threading (and  
strictly that) portably using FFI, threads are not a library feature.  
Threads are a language feature. For threads to be useful and  
trustworthy, you must fully specify a boat load of things, from  
atomicness of stores to memory barriers and observable store/load  
ordering.
