* A list of globally installed [CoroutineExceptionHandler] instances.

* Note, that Android may have dummy [Thread.contextClassLoader] which is used by one-argument [ServiceLoader.load] function,

* see (https://stackoverflow.com/questions/13407006/android-class-loader-may-fail-for-processes-that-host-multiple-applications).

* So here we explicitly use two-argument `load` with a class-loader of [CoroutineExceptionHandler] class.
