ci(enable-fork): set fork interval to 10 seconds #3694

Closed Tang-Haojin closed 4 weeks ago

This change can help us to capture the waveform of problem caused by hardware stuck. Besides, since we enlarged mmap memory, it may take much more time on fork() syscall. Enlarging the fork interval here also results better simulation speed in some circumstances.

Some profiling evidences here. When I add -X 10, the CPU usage can reach 100% approximately.
