 Haiku of the month:
 
-  Many jobs to run.
+  Programs very slow.
-  Idle cores is not your thing.
+  Multiple can run at once.
   Use GNU Parallel.
       -- Ole Tange
 
 New in this release:
 
-* Security: The security issue for --sshlogin + --fifo/--cat has been fixed. Thereby all issues with http://lists.gnu.org/archive/html/parallel/2015-04/msg00045.html have been fixed.
+* <<afventer opdatering>> CIDER: a pipeline for detecting waves of coordinated transcriptional regulation in gene expression time-course data http://biorxiv.org/content/biorxiv/early/2015/03/17/012518.full.pdf
-
-* Security: After further security analysis the issue fixed in 20150422 also fixed the problem for --tmux.

+=head2 Killing jobs
+
+B<--memfree>, B<--halt> and when GNU B<parallel> meets a condition
+from which it cannot recover, jobs are killed. This is done by finding
+the (grand)*children of the jobs and killing those processes.
+
+More specifically GNU B<parallel> maintains a list of processes to be
+killed, sends a signal to all processes (first round this is a TERM).
+It weeds out the processes that exited from the list then waits a
+while and weeds out again. It does that until all processes are dead
+or 200 ms passed. Then it does another round with TERM, and finally a
+round with KILL.
+
+  pids = family_pids(jobs)
+  for signal in TERM, TERM, KILL:
+    for pid in pids:
+      kill signal, pid
+    while kill 0, pids and slept < 200 ms:
+      sleep sleeptime
+      pids = kill 0, pids
+      slept += sleeptime
+      sleeptime = sleeptime * 1.1
+
+By doing so there is a tiny risk, that GNU B<parallel> will kill
+processes that are not started from GNU B<parallel>. It, however,
+requires all of these to be true:
+
+* Process A is sent a signal
+* It dies during a I<sleep sleeptime> cycle
+* A new process B is spawned (by an unrelated process)
+* This is done during the same I<sleep sleeptime> cycle
+* B is owned by the same user
+* B reuses the pid of the A
+
+It is considered unlikely to ever happen due to:
+
+* The longest I<sleep sleeptime> sleeps is 10 ms
+* Re-use of a dead pid rarely happens within a few seconds
