[CentOS] semi-OT: perl question

We've had a ton of selinux errors recently, and the other day, one of the
managers here, after I started inquiring what their perl CGI was doing,
found a way to reproduce the issue at will. It seems that before I
upgraded their servers from CentOS 5.x, they were trapping interrupts such
as a browser breaking the connection before getting a response, and under
CentOS 6, it's looking like the traps aren't working.

Has anyone seen anything like that?
