+KNOWN ISSUES
+------------
+
+- `{fputc,putc,putchar}_unlocked()` are not hooked when writing to stdout
+ (which might be redirected to stderr). Can't be fixed as the compiler
+ inlines the code into the program without calling any function.
+- Test `test_stdio.sh` fails for this reason on FreeBSD.
+- 'COLORED_STDERR_IGNORED_BINARIES' requries the `/proc` file system.
+ Suggestions welcome.
