No, it has nothing to do with reference cycles. The issue is that most C
functions accepting callbacks with a user_data pointer don't accept an
additional pointer to a free function for the user_data pointer. This
would be necessary to support closures with allocated user_data, though.

While it's theoretically possible, it'd probably have more disadvantages
than advantages for Vala, especially for Vala libraries.
