searched the thread, threading module for a function for generally 
locking/dislocking all other python threads from execution. Did not find 
something like that.

(That would be very useful in some threading applications to protect 
critical sections without forcing the whole application to be populated 
with lock objects.
Of course, such function should be used with care (and "finally")  - but 
it should be there to make thread programming easier...)
