+# 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

+# +B [c | d | i]
+# Option c makes Ctrl-C interrupt the current shell instead of invoking the emulator break
+# handler. Option d (same as specifying +B without an extra option) disables the break handler. # Option i makes the emulator ignore any break signal.
+# If option c is used with oldshell on Unix, Ctrl-C will restart the shell process rather than
+# interrupt it.
+# Disable the emulator break handler
+# it easy to accidentally type ctrl-c when trying
+# to reach for ctrl-d. ctrl-c on a live node can
+# have very undesirable results
