It just happens for me each time - on Fedora 27 x86_64 on 16-core (32HT) 2-node NUMA machine having env var `MAKEFLAGS=-j32` (and `tuned-adm throughput-performance` if it matters). Comparing multiple runs makes some tests {Expected,Unexpected,}{Success,Failure,Error} without changing anything.

When the testcase is then ran separately it sure succeeds as the machine then has no load that time. 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.
