in thread can a script change itself?

I know "multiple concurrent user safety" wasn't part of the specs of this question, but I thought it would be good to give a word of warning here anyhow. I've been bitten before by race conditions when using cook-book (aka cut-and-paste) style programming before.

I learned one lesson in my intro to concurrency course: "Concurrency is hard." There are few, if any, concurrent debuggers in existance ( one grad student was working on one, with some limited success), and the very convenient rule that states "if I run the same program, with the same inputs, I'll get the same output" goes out the window, because other programs can interfere.

Avoid concurent programs when you can: when you can't, swear loudly and quadruple your delivery date.
