[Python-Dev] doc change for weakref

Fri May 25 19:21:39 CEST 2012

I'd like to make a slight doc change for weakref to state (more or less):
 weakrefs are not invalidated when the strong refs
 are gone, but rather when garbage collection
 reclaims the object
Should this be accurate for all implementations, or should it be more 
along the lines of:
 weakrefs may be invalidated as soon as the strong refs
 are gone, but may last until garbage collection reclaims
 the object
