A UI can have it's CLW (CL Window...) register for events about
profile changed, but it's not mandatory.

It's not done with gobjects, just plain python code, no threading, no
real event loop... look at the code ;)

Yes, and maybe have a "priority list"... this sucks... i don't know
how to fix that.

No, i meant :
core.profile.nick = "LoL :p"
just like :
22 @property
23 def rad():
24 '''The angle in radians'''
25 def fget(self):
26 return self._rad
27 def fset(self, angle):
28 if isinstance(angle, Angle):
29 angle = angle.rad
30 self._rad = float(angle)
