No. According to POSIX, exec* has no reason to fail if other threads
are still running in the current process. These other threads are
terminated. With system threads, Caml's Unix.exec* functions just
call the corresponding system calls.
If you want to make sure, you could try to reproduce this behavior
with a small C program.
