get return or locals from "exec" str in "environment"

oh, yeah that was perfect.  got it working and it is graceful too.  sorry about the double post, i thought i was only posting to this one.

one final concern, if this code is running under a function in a multi-threaded, multi-session kind of environment, does exec cross threads or sessions?  like, i am afraid that i will get cross-over or bleeding into other threads or sessions.  does exec do that kind of common memory space wherein i have to be very very careful about executing such code and my daemon crashing or security holes and the like.
