+
+Comparing to GNU/Linux, on GNU/Hurd it happens much more often and easily for
+*screen* sessions to become *dead*. This is annoying, as it defeats one of
+*screen*'s main purposes.
+
+One reproducible scenario goes like this:
+
+ * `ssh [somewhere]`,
+
+ * start a *screen* session, and some long-running process *P* in there,
+
+ * at some point the link is forcefully terminated (also known as disconnect
+ after 24 hours with consumer DSL),
+
+ * *P* will continue to execute,
+
+ * at some point, *P* will terminate / hang (after having received some kind
+ of signal?), and the *screen* session will be reported as *dead*.
+
+Another one, not as often reproduced:
+
+ * `ssh [somewhere]`,
+
+ * start a *screen* session, and some long-running process *P* in there,
+
+ * at some point the link is forcefully terminated (also known as disconnect
+ after 24 hours with consumer DSL),
+
+ * `ssh [somewhere]`,
+
+ * `screen -x`, and notice that *P* will *immediatelly* terminate / hang
+ (after having received some kind of signal?), and the *screen* session will
+ *immediatelly* be reported as *dead*. (Perhaps the other way round: upon
+ re-attaching, the *screen* session goes bonkers and takes *P* with it?)
