BTW, this is an awesome project. And I wonder whether it is still maintained because I really want to have the "snapshot execution" capability in my current project.

The test2 program is just a "sleep and then puts hello world" program

It turns out that the ecfs file generated by ecfs_snapshot is corrupted. The ecfs file generated by sigsegv handler is more correct -> still not able to re-execute it.
