Yes, that should all be fine, because the IORef is only modified from one
thread, and read from the other(s). If you were modifying the IORef from
more than one thread you would need to use atomicallyModifyIORef, or MVars.
If I did modify the IORef from more than one thread (e.g. if a bug were
introduced), would this cause any trouble other than occasional missed
updates or reads of wrong data?
It shouldn't, no.
