No, it's not thread safe unfortunately. There's no general mutex
locking mechanism for data in Blender, which I guess is would be the
typical way to implement this. On the Data API side it would be
relatively simple to implement, but all the other Blender code
accesses data without any checks, and making that thread safe would
require changes all over the code.
