boost::shared_ptr is thread safe.

I'm pretty sure that...
new calls the "operator new()" function
delete calls the "operator delete()" function
and there are alternate ways of calling new() :

http://www.research.att.com/~bs/glossary.html#Gdelete
As for managing your memory, lots of people will point to one of the
boost smart_ptr's or something similar :
http://www.boost.org/libs/smart_ptr/smart_ptr.htm
But nobody seems to agree on whether or not those are thread-safe. What
I'm getting at is that Gtk::Manage was meant for widgets. If you have
objects that are not derived from Gtk::Widget I don't know if that will
help you at all. Read through the Memory Management section of the
Gtkmm book :
