Description Hiroki Noda 2018-08-06 13:32:45 UTC 
It's a possibility that rewriteing global variables may be performed by singal handler,So set signal handlers are reset to SIG_DFL.
In order to prevent race condition, it is necessary to mask signals once in the parent process before fork.
Comment 1 Hiroki Noda 2019-07-25 07:53:50 UTC 
I'm wrong, we don't have to care about race condition in this case when we don't use vfork().
