Alright. Thanks for clarifying. Is that a guarantee that holds for all classes marked reentrant in Qt? (that const functions are safe even when called on the same instance) If so, maybe the docs page I linked should be updated to mention this [1]. I thought that Qt wanted to reserve the right to do thread unsafe stuff even in const functions, and that was the reason for the definition of reentrant explained there.
