ISTR those settings from that priority mapping documented somewhere -
winsup/doc/specialnames.xml pathnames-proc "The /proc filesystem" proc(5) 
/proc/PID/stat (18) priority and (19) nice - which are generated as proc.5 and 
cygwin-ug-net/proc.html for cygwin-doc package.

Package man-pages-linux also has /usr/share/man/linux/man5/proc_pid_stat.5.gz 
which it would be good to compare set see if there were conflicts?

It would be good to state in a release note what has changed in the mapping or 
effect e.g. SCHED_OTHER now uses only NICE and SCHED_FIFO/RR use only PRIORITY?

I will have to search my Cygwin docs and code to see where things are mentioned 
or used.
