I'm not sure I understand this.  Why is using a temporary handler better

I just want some way to not ignore the signal. For example handle the
signal after initialization of trap even if the signal is delivered
during this initialization.
I don't think you are understanding what I'm proposing.  Blocking the signal
with sigprocmask(SIG_BLOCK, ...) does the right thing.

I didn't understand, but now I do. Thanks for clarification and sorry...
