The prompt should not be printed until the last statement entered has
been completed.

fry sez: here's what I mean by really obvious:
When I execute the current file in the shell, don't print
[evaluate foo.py]
"Evaluating foo.py ..."
and when its done, print the value of the last expression in the file
followed by 
"foo.py loaded."

This shouldn't be happening unless, perhaps, if threads are involved.

Currently there isn't a way to break into a loop.  This is something we
need to add.  As a workaround, you may want to run code in the debugger.

Fry sez: Yes I toggle back and forth between the debugger and the shell because
neither is good enough. I'd be happy to help you on designing it so that it is.
I've done that a number of times before.
