This has been reported (and allegedly fixed) before, e.g. #78957, but it is still true.

After around 100 hours, getrusage() stops counting.

The attached demo stopped with output:

... [381082, 999593]T10.6742 1 [381093, 671972]T10.6724 0 [381104, 363990]T10.692 1 [381104, 363990]T0 0 [381104, 363990]T0 1 [381104, 363990]T0 1 [381104, 363990]T0 1 [381104, 363990]T0
