I didn't consider that this might be a limitation. Hmm...

You know a lot more than I do about implementing this sort of things. Do
I understand it correctly if I think that adding locking/unlocking would
mean that file accesses from the main thread would remain unchanged, but
that the mixer would need to lock/unlock the file handle it streams sound
from to ensure that it doesn't change in mid-stream?

I take it, then, that just about every function in the File class would
need to wait for the lock to be released before doing anything.
