Hmm. That new test is meant to make sure that the syscall entry/return
state is not lost across an execve. In the failure I knew, the execve
return was interpreted as an additional syscall entry. But in the cases
you've shown, it didn't catch syscall return from execve at all!
I will investigate more...
