Is it actually possible to build a "sandbox" around eval, permitting it

I have an application that loads calculation recipes (a few lines of
variable assignments and arithmetic) from a database.
exec(string, globals, locals)
with locals containing the input variables, and globals has a
__builtin__ object with a few math functions. It works, but is it safe?
There have been some attempts, but they've all been defeated.
