[Catalyst] RFC: C::P::Alarm (was Re: timeouts)

[Peter Karman]

Coming soon to your local CPAN mirror: Catalyst::Plugin::Alarm

The Alarm plugin implements Sys::SigAction for Catalyst. It uses the 
Catalyst::Alarm namespace, and adds 2 methods to the Request object: 
timeout() and alarm().

If you Just Can't Wait, you can get it here:

Comments & patches welcome.
