Doubt regarding Signals

[Shameem Ahamed]

Hello Friends,

This question is not relevant to glibc specific.  

I have one doubt regarding the signal handling mechanism in Linux.

If  a process receives more than one different signals (eg SIGUSR1 and SUGUSR2  or any two other signals) simultaneously what is the default action from kernel. Which handler will execute first and what is the criterion for selecting the handlers for execution
