I'm not convinced - it seems like overkill to me.

I would initially investigate on why emails are taking so long to send.
Can you deliver the email locally instead? That should happen with very
little noticeable delay. It's then effectively asynchronous, as the
local mailer will be attempting to send the email whilst the web
application continues to run.

Have you loaded a suitable guard module (e.g. Guard or Scope::Guard)?
Otherwise (from memory) the application will exit before it raises an
exception of the missing guard function.
