I didn't succeed in getting any more yet. 

But I did get a stamp-propagation-test failure on SBCL/Linux (attached). 

There is also a test-multiple failure in there, but that's because I am running Linux in a mounted VM guest filesystem which doesn't allow symbolic linking (it comes back with "Read-only Filesystem" when you try to make a symbolic link in an OS terminal shell). I wonder if this test can query the OS somehow to see if the current filesystem allows symbolic links, and don't try to make them if not. 

Also attached is a patch which makes the output *.text files in build/results/ be os-specific, to allow for running the tests in the same asdf/ directory mounted across multiple machines. 

There are other outputs (e.g. fasl cache directories) which I feel also ought to be named in an os-specific manner, to support running the tests from a common directory across all machines. But the bootstrapping issues involved with that are a bit beyond obvious to me at first glance --- presumably some of these names would have to be determined in script-support.lisp, before asdf is loaded with its "detect-os" etc. goodness. So I guess a subset of that functionality would have to be copied into script-support.lisp.
