#  Synospsis:
#	Report of running flowd processes in schema/*/run.
#  Usage:
#	run-stat-report
#  See:
#	setspace/sbin/run-stat-tuple
#	setspace/sbin/run-stat-tuple .	#  limit stats to schema in current dir/
#  Note:
#	Replace "column" command with gnuversion in util-linux macports
#	or write replacement in https://github.com/jmscott/work.
#
#	Ought to consolidate this script with blobio/sbin/run-stat-report.
#
#	Sort is ignoring the second key on linux.  The pain never ends.
