Home Memory consumption concern regarding asynchronous code in Perl
 I'm running a Perl web server which needs to do some work asynchronously. For this, I use the threads module in the following way: threads->create(sub { # Asynchronous code here threads->exit(); });  I have some concerns regarding the correctness of this. Whenever I exit the server, I get the following message: Perl exited with active threads: 0 running and unjoined 1 finished and unjoined 0 running and detached  I guess this has to do with the fact that I didn't joined or detached my thread. Detaching my thread would be a good solution but, unfortunately, it triggers this: https://bugzilla.redhat.com/show_bug.cgi?id=548249. Now, here are my questions. Is there any problem with running the thread without joining or detaching it? Is it going to be a memory leak because of the unjoined/undetached threads? Should I run some cleanup code to take care of the finished threads? Thank you in advance!
