+Try to inline flowgraphs based on whether doing so would enable malloc
+removal (config:`translation.backendopt.mallocs`.) by eliminating
+calls that result in escaping. This is an experimental optimisation,
+also right now some eager inlining is necessary for helpers doing
+malloc itself to be inlined first for this to be effective.
+This option enable also an extra subsequent malloc removal phase.
+
+Callee flowgraphs are considered candidates based on a weight heuristic like
+for basic inlining. (see :config:`translation.backendopt.inline`,
+:config:`translation.backendopt.clever_malloc_removal_threshold` ).
