+* How to Debug
+Since we're using the Boehm GC, in order to use a debugger we need to turn off some of the signal
+handlers that the debugger sets. In order to run the debugger (by default lldb) with ~serenec~
+just use the ~lldb-run~ subcommand of the builder script. In the debugger, after setting the
+break point on the ~main~ function (~b main~) then use the following commands on:
+
+  #+BEGIN_SRC bash
+   process handle -p yes -s no -n no SIGPWR
+   process handle -p yes -s no -n no SIGXCPU
+   process handle -p yes -s no -n no SIGSEGV
+  #+END_SRC bash
