P3-1: releasing a console start lock marks it released through its own
descriptor and removes the path only while it is still that file; a
released lock put back by a racing clear is cleared by the next start or
stop.
P3-2: org definitions reports unknown-organization only when the
organization file itself is missing; another missing file names the
operation.
P3-3: the path cut also covers a path after ':' or inside backticks.
