            Bug ID: 40047
           Summary: [macOS] TestConcurrentSignalWatchBreak.py fails
                    spuriously
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs

Created attachment 21235
  --> https://bugs.llvm.org/attachment.cgi?id=21235&action=edit
output of test execution

Executing 'ninja check-lldb' produced a fail in
TestConcurrentSignalWatchBreak.py. 

However, when I executed the test with './bin/lldb-dotest -p
TestConcurrentSignalWatchBreak.py' the test passed. So, this test sometimes
fail, sometimes pass. I suspect some thread synchronization issue or a
wait/poll problem here.
