+# from other libraries. Generally, I'd expect a very few __functions
+# with two underscores to be exported and not used by e.g. libc-X.X.X.so,
+# as these names are supposed to be internal, i.e. external programs
+# usually don't call them. On my system, I got 141 such __functions.
+# Examples:
+# __flockfilelist - NOP function (why do we need it at all?)
+# __pthread_perform_cleanup - called only from within libpthread
