If for example C++ calls a D function, the D function does 
something temporary with arrays then those arrays will not be 
cleaned up if the array memory is thread local.

More likely since the thread has no meta data in D, some error 
will happen. The programmer will sure know it but this is very 
inconvenient as the D function will not work if called outside D.
