All of the above except c) and d), I think.

You might like to Google for something like

   Brett Cannon secure Python

to get up to speed on some work that may eventually result in Python 
acquiring a more security-minded framework. Bastion and rexec were so 
full of holes you could drive a London double-decker bus through them, 
so their deprecation and eventual exclusion was felt to be safer than 
leaving them in to be mistaken for secure code.
