I have now uploaded util-linux 2.40.2 as a test release.  See the 
announce AT cygwin DOT com list for the announcement.

This release does not have a dependency Cygwin >= 3.6.  /usr/bin/chrt 
now understands the options for SCHED_IDLE and SCHED_BATCH policies, but 
they are not effective unless you're running on 3.6 or greater.
