   I'm sorry to hear that you encountered a regression.
   
   As far as I can understand how posix signals are supposed to work, this should have fixed the  situation where the signal action is never performed if the signal is masked, or if system calls are in use.
   
   My understanding of the posix signaling spec is that if a signal action is masked, it should be put into the pending queue no matter what. I am not sure about this though. Maybe someone who knows more about this subject can comment?
   
   @xiaoxiang781216 the revert should take into account what this patch was supposed to fix; the signal action should not be pended twice.
