If the Go signal handler is invoked on a non-Go thread not running Go
code, the handler generally forwards the signal to the non-Go code, as
follows. If the signal is SIGPROF, the Go handler does
nothing. Otherwise, the Go handler removes itself, unblocks the
signal, and raises it again, to invoke any non-Go handler or default
system handler. If the program does not exit, the Go handler then

The built-in handlers acquire a lock before calling [io.Writer.Write]
to ensure that exactly one [Record] is written at a time in its entirety.
Although each log record has a timestamp,
the built-in handlers do not use that time to sort the written records.
User-defined handlers are responsible for their own locking and sorting.
