Maybe one could make some race reproducer helper (such as was GDB read1 <https://sourceware.org/bugzilla/show_bug.cgi?id=12649>) but I should analyse more LLDB testsuite races to know the common racy issues in LLDB testsuite.


That sounds a great helper. Any chance you're interested in working on that? I don't have access to a machine beefy enough to repro the failures, I'm afraid.
