-/// As always - iOS on arm uses SjLj exceptions and
-/// _Unwind_Backtrace is even not available there. Still,
-/// backtraces could be extracted using a backtrace function,
-/// which thanks god is public
-///
-/// As mentioned in a huge comment block in `super::super`, backtrace
-/// doesn't play well with green threads, so while it is extremely nice and
-/// simple to use it should be used only on iOS devices as the only viable
-/// option.
