net: no way to lower listen backlog on a TCP listen socket

[gopherbot]

by vinay.ys:

While writing a tcp server one may need to set the tcp listen backlog to a lower value
than the system default. There don't seem to be any API available in net package to
accomplish this.

Which version are you using?  (run 'go version')
go version devel +d3f99f091748 Tue Jun 25 17:04:18 2013 -0700 linux/amd64

Comment 1:

One workaround is to create the socket yourself using syscall.Socket, syscall.Bind and
syscall.Listen and then use net.FileListener. Not ideal though...

Yes, that is an acceptable temporary workaround. My primary use-case is a net/http
server. For that this workaround is more than a few lines of code.

I'm trying to reduce the number of connections waiting in the listen backlog of a daemon
I wrote using net/http.
