Or you could use a semaphore file: when finished, the sub-procedure places a file somewhere at an agreed place and the main program watches until the file appears and then does the clean-up (including deleting the semaphore file).

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
