This is a feature of execve that probably cannot be similated by Valgrind,
see coregrind/m_syswrap/syswrap-generic.c from line 2419. The name of the
exe actually executed is in ARG1, the name to be shown to the user in
ARG2[0]. execve.c passes NULL in ARG2[0], preventing recursion. There
seems to be no way to tell Valgrind with --trace-children=yes to do the
same.
