Actually, I've found that
--------
package main
import "syscall"
func main() { syscall.Write(1, []byte("Hello World\n")) }
--------
also crashes ~66 syscalls after the first sysarch(2) call.  That
reduces the binary to 520K (go reports this is 50K lines of assembler).

I've uploaded the source, binary and disassembly to
freefall:~peterj/write{.go,,.S} (and verified it crashes).

If I get time, I'll see if I can strip some of the support code out of
Go to shrink it further.
