NSTextSorage is mutable object.

Documentation>Cocoa>Resource Management>Multithreading>Thread Safety
says...

Immutable objects are generally thread-safe. Once you create them, you can
safely pass these objects to and from threads. On the other hand, mutable
objects are not thread-safe. To use mutable objects in a threaded
application, the application must synchronize appropriately.

I always wish if I could use mutable objects in multi-thread....
