Hmm, this gives me an idea. There's nothing, I believe, that makes the root user
have to have the name "root" except for the passwd file. Maybe I'll just
rename "root" to "walley" and then use "root" as my normal account. If anyone tries
to break into "root" they will just gain access to a normal account and nothing
more ;-)

/me goes back to hacking

perf tools: Use the DWARF unwind info only if loaded

Use the info only if it has been found in the .debug_frame section of
the ELF binary.
