Why not easy Thread synchronization?

[Iwan van der Kleyn]

It's very easy writing simple  threaded programs in Python. In fact, its 
part of my "evangelize demo's" :-)
However, thread synchroni(s/z)ation seems to be a bit more fussy and 
complex then,  for example, Java.

Why not a "synchronization" reserved word like in Java which takes care 
of "scary" bits under the hood?

For example:

sync def log(s):  #in which the hypothetical keyword 'sync' makes the 
function 'log' thread safe
	sys.stout.write(s)
	sys.stout.flush()

Seems to be a bit more fitting to Python mucking about with locks and 
mutexes.
