+##############################################################################
+
+# NOTE
+#
+# If a signal occurs in the very short window between pmnslock returning and
+# setting haveLock, the lock is not released by cleanup(). Any subsequent
+# process calling pmnslock will block until its pmnslock steals the lock
+# (currently after 120 secs). That window is carefully minimised.
+#
+# Past versions of similar scripts (e.g. Rebuild) unconditionally unlocked the
+# namespace when a signal was caught. This could potentially happen while
+# still waiting to acquire the lock, breaking a lock held by another process!
+#
+# Consider locking and backup/restore implications carefully if making changes.
