<pre>All of the tests involving multiple breakpoints suffer from randomly
establishing the wrong breakpoint hit count, e.g.:
FAIL: LLDB (/home/mgorny/llvm-project/build.arm64/bin/clang-aarch64) :: test
(TestConcurrentTwoBreakpointThreads.ConcurrentTwoBreakpointThreads)
======================================================================
FAIL: test (TestConcurrentTwoBreakpointThreads.ConcurrentTwoBreakpointThreads)
Test two threads that trigger a breakpoint.

It seems to be a problem in lldb/lldb-server logic somewhere that needs further
debugging.</pre>
