Oh so this is why the tests on Windows suddenly printed version numbers then :)

The pitch sounds great I'm all in but yes I don't think there's a single place on Linux that fits right now. System log being a NOOP isn't a regression for Linux either. If/when Swift on Linux or some other LLDB distributor wants to get the same benefits as Mac, they can suggest a solution.

If this uses the existing logging infrastructure, I presume it is possible to give a user a command to enable lldb's system log and re-run the reproducer? It would be the same as sending any other channel to a file.
