+# opend by run_erl. Useful if you want to remove any risk of accidentally
+# blocking the flow control by using Ctrl-S (instead of Ctrl-D to detach),
+# which can result in blocking of the entire Beam process, and in the case
+# of running heart as supervisor even the heart process becomes blocked
+# when writing log message to terminal, leaving the heart process unable
+# to do its work.
