`tester.tcl` works fine on all *nix targets for us. The problem manifests only on Windows. > tester.tcl seems to work fine on every machine we run it on here. No disrespect intended, but may I ask if there are also Windows machines in "every machine"? I presume they are and that would imply there's something to fix on Go side. I'm just trying to clarify this so we know which area to look into before digging into it more. Thank you for your kind cooperation!
