Re: Problem with infinite loop in signal handler

Hello,
Not exactly infinite loop but sigsuspend. Infinite loop was only
example to show the problem. Without printf in sig handler problem
also occures.
I am writing simple stop-the-world garbage collector so I need this
construction to stop (almost)all threads in application. I think only
solution for this problem is not using any stream that client
application may use.
Thanks for help anyway :)
