I think the best course of action would be to incrementally do away with
the shell scripted test framework, in the way you outlined earlier this
year. This would *also* buy us a wealth of other benefits, such as better
control over the parallelization, resource usage, etc.

If you have not noticed, I'm a bit busy with all sorts of stuff and
probably won't continue that work. And since it affects you the most,
you probably have the best motive to tackle it ;-) I don't think
complaining about slow test suite helps. And avoiding adding more
tests because of that definitely does not help.

It would also finally make it easier to introduce something like "smart
testing" where code coverage could be computed (this works only for C
code, of course, not for the many scripted parts of core Git), and a diff
could be inspected to discover which tests *really* need to be run,
skipping the tests that would only touch unchanged code.
