I guess it's the following entry in CHANGES:
add a workaround that clears undertime when a class is
resumed to avoid eventual outage under a long stress test.
somehow, the kernel timer expires earlier than the expected
time under certain conditions on FreeBSD (the cause of this
phenomenon is not known).
when this happens, a resumed class could get suspended
immediately after its resume for another offtime.
