g_threads_enter() equivalent

[Talguy <talguy385 gmail com>]

I was wondering if there is an equivalent function to g_threads_enter()/leave() in gtkmm.  Is gtkmm thread aware like gtk+ is.  Reason why I would like to know is I want to port the multi threaded animation example of cairo's site to gtkmm to better help me out in my animations.
