[pgpool-committers: 8504] pgpool: Allow shutdown interrupt while processing SIGCHILD in pgpool ma

[Tatsuo Ishii]

Allow shutdown interrupt while processing SIGCHILD in pgpool main.

Currently most signals are blocked in pgpool main loop. In some
situations the SIGCHLD handler (reaper()) takes long time or blocked
in wait system call. I suspect that this could cause occasional
timeout in some regression tests. So allow interrupts while executing
reaper(). Also re-implement CHECK_REQUEST macro as a function. There's
no point to implement CHECK_REQUEST using macro.
