…g events too frequently (pythongh-141845) If we overflowed the global version counter (i.e., after 2*24 calls to `_PyMonitoring_SetEvents`), we bailed out after setting global monitoring events but before instrumenting code objects, which led to assertion errors later on. Also add a `time.sleep()` to `test_free_threading.test_monitoring` to avoid overflowing the global version counter. (cherry picked from commit e457d60) Co-authored-by: Sam Gross <colesbury@gmail.com>
