well, i must say i don't know exact specifics. but as i get it vala should
free memory by it self. as soon as your ref count per any object falls to
zero memory manager vala should dispose it. and that should happen at the
end of code block. in my eyes following the previously suggested of not
taking care should work as it should.

but if you want to be sure, doing something like
myobject.weak_ref ((o) => { stdout.printf ("my object disposed"); });
should answer this better if you test it for your self. if you connect
this signal you will see if finalizing was executed or not when program
exits.

method simply calls
http://www.gtk.org/api/2.6/gobject/gobject-The-Base-Object-Type.html#g-object-weak-ref
which is called upon finalizing without deadlocking that object.

yes, it is... for c and likes, but in language where memory is garbage
collected like in vala, question should be completely unreasonable
***unless your code manually allocates memory***. if there is a memory
leak, it has to be fixed in memory manager.
