Hi Amit,

>1.   I created a global variable named "QuitThread" on my main module.

This sounds wrong. You don't need QuitThread as a parameter to

>5.   This function runs a loop in which it checks every iteration

>6.   If it is True, it executes "thread.exit()".
>7.   Nothing happens. The thread continues on running.

has your problem been solved in the mean time?
If not two things to check/try:
- thread.exit works by throwing an exception. Make sure you don't
  catch it by accident.
- Print/log value of QuitThread on every access in both threads.
