In Gentoo the suggested setting is

And checking around seems that there are people suggesting
something even larger.

On MacOSX it seems working fine.

If I recall correctly setting something larger that the os limit
won't make the call fail so this patch shouldn't hurt even for
those setup, right?

Worse; it will make the call fail silently. The only way to be sure
you've set it correctly is to getsockopt() and check if the value is
what you requested. :|


So what's the best course of action?

- Bump the size to be twice as big instead of 5 times
- Set the option twice
- Something else completely different

Ignoring the issue is not an option =)
