Subject: memory leaks?
EV installed AnyEvent::HTTPD 0.5 installed Both were installed from CPAN with the default options. Running the standard example from http://search.cpan.org/~elmex/AnyEvent-HTTPD-0.5/lib/AnyEvent/HTTPD.pm#SYNOPSIS causes the perl process to continue to grow in memory. It seems like a leak. I ran ab -n 100000 -c 100 http://127.0.0.1:9090/ 4 times in a row. The perl process grew in resident memory size by about 20 MB for each run. Yes, this is a stress test but it shouldn't leak memory, right?
