Subject: [PATCH] - add checkAlarms function - this function will be used to
 determine wether expiration alarms are active. If qemu dies or terminates
 unexpectly, this function will check if it was before an timeout. In that
 case alarms will be active. Note: if qemu is killed purposely,
 OsSupport::cancelAlarms must be called to prevent automatic termination of
 sysreg process
