Go Auto-Recompile and Reload Server on file change

Question

I know AppEngine does this, but I'm not coding for it.

I tried using Guard from Ruby world, to listen on changes on .go files, and execute the following commands:

killall foo
go build -race
./foo &

But it never sends foo into background, it just hangs indefinitely.

How are you guys solving this problem? Solution has to be cross-platform too (GNU/Linux and Mac).

A friend wrote a simple Compile Daemon for go, worked like a charm for my own small net/http-projects.
