Comment(by acleone):
I'd like to work on this patch. At this point we're doing a lot more than
just replacing the display hook hack - what should the scope of this patch
be?
(Tom, correct me if I'm wrong) The patch currently:
1. Replaces the display hook hack with a much more robust implementation
using python's [http://docs.python.org/library/ast.html ast library].
2. Adds a new process implementation that passes a data object across
* The old implementation passed a string to get exec-ed. The string
was "write this base64 encoded string to a file and exec it".
* The new implementation gets the data object, writes the preparsed
string to a file (just so exec will have line numbers), and exec's the
string. This is faster because it's only one exec.
