Thanks for the suggestion. I will try that and see if it works. My concern 
is that one thread might be e.g. writing to a file, and in that case I need 
to way for it to finish. By using a flag this should work.

Another thing that comes up, is about signal handling. Would there be any 
limitations in say using signals in Windows compared to UNIX?

(I am thinking about setting up a signal handler that changes the flags in 
all threads.)
