+# Compilation of rl_code.c is really slow (about 26 minutes on traveller with
+# --trace deep) at the default level of -O2, due to the C optimizer's use of
+# quadratic algorithms on a couple of 20,000-line functions (the automatically
+# generated index and compare routines on the bytecode type). The code in this
+# module can't really benefit from those algorithms anyway. With -O1, the 26
+# minutes drops to less than 26 seconds.
