+* LLDB now supports hardware watchpoints for AArch64 Windows targets. Windows
+  does not provide API to query the number of supported hardware watchpoints.
+  Therefore current implementation allows only 1 watchpoint, as tested with
+  Windows 11 on the Microsoft SQ2 and Snapdragon Elite X platforms.

I am not actually sure about the cause but `-j1` doesnt really fix the issue with test failures. This appears to be somehow while running the testsuite in batch mode we somehow start python with different set of permissions. Although thats just a guess I do not have evidence supporting that claim.
