select timeout

[Michael Hoisie]

I noticed that select doesn't have a timeout mechanism. What's the
best way to add one?

In my scenario I'm running a few processes on goroutines, and using a
blocking select to wait for all of them to finish. However, the
processes might take a long time to complete, and I'd like to have a
timeout on the select call. I could have a separate goroutine that
sends heartbeat signals, but that seems like a lot of work.

In the traditional unix select, there's a timeout argument. Would that
be something useful to add to the language?

In the meantime the heartbeat signal generator has already been
written for you: time.Tick returns a channel that you can use in
select.
