That's why I don't regard managed langues and environments (C# and Java),
because they made programmer a lazy person. C# programmers don't bother
about memory, don't bother about CPU time, generally don't bother about
anything. I'm a C programmer and I used to bother about anything, because I
always assume, that  it's better to do things on my own and don't assume,
that someone/something will do it for me.

I investigated generated C code, toplevel window must be destroyed manually
with destroy() method before destroying Gtk.Builder object holding this
window. Where to report this "bug" in example? On Bugzilla?
