Feature #9346: [PATCH] signal.c: avoid repeated disable/enable interrupt
https://bugs.ruby-lang.org/issues/9346

Author: normalperson (Eric Wong)
Status: Open
Priority: Low
Assignee: 
Category: 
Target version: current: 2.2.0


We only install system-level signal handlers during init (before any
threads or user code is running), so there's no need to repeatedly
enable/disable the interrupts at that time.  We also do not change
system-level sig handlers once user-level code is running.

This saves about 20 syscalls at startup and makes the executable
smaller:

text       data     bss     dec     hex filename
