exceptions, etc). Any exception may still come out of that nothrow overload;
technically including the specific exception if it came from somewhere else!
When no exceptions whatsoever are expected, the `noexcept` keyword is used.
Use the noexcept keyword with tact, not by default. Most of the project
propagates exceptions. Functions that handle their errors and are expected to
return (i.e since they catch `std::exception`), still throw special exceptions
like `ircd::ctx::terminated`. If the `catch(...)` and `noexcept` features are
used: developers must cooperate by handling ctx interruptions and propagating
terminations. This is not an issue on leaf and simple functions where we tend
to make use of `noexcept`, especially for non-inlines allowing for better
compiler optimizations to occur.
