Программка тестирования на блокировку прерываний
Написал программку для наглядной демонстрации и выявления данной проблемы. При
запуске её на ALTLinux3.0 и SuSe 10.1 четко видно блокирование быстрого таймера
в ALTLinux3.0 на момент исполнения потока медленного таймера.

Эта проблема, кстате, актуальна и для ALTLinux 2.4. Проблема не актуальна для glibc-2.5-alt4 из Сизифа. Закрываю как не актуальный для 4.0 |
