I disagree - it's usually a good idea to write log records
etc. first. Otherwise there's a risk that a message would be frozen
but noone would be told, which would be bad.

Possibly you want to suspend certain signals (HUP and TERM are
traditional) at certain points. A really paranoid thing might be
always to disable TERM inside things that should be `atomic'.
