This is often a costly operation: 1.3 - five situations slower for synchronous loggers. Synchronous loggers wait around as long as possible just before they acquire this stack snapshot. If no locale is needed, the snapshot won't ever be taken. Even so, asynchronous loggers will need to create this choice before passing the log information to a different thread; The placement data will be lost following that place.
