* signal.c: avoid repeated disable/enable interruptnormal2014-10-281-5/+5
| | | | | | | | | | | | | | | | | | | | | | | 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.
