- Why can't I get /proc/cmdline to work nicely?? (ps -x shows messed up things after stack is restored,
  ps -a shown nicely)

- Have to stop at main() for static programs!! Should I read main from the symbol table??

- in savefds.c,  when I do a readlink ... is it possible for /proc/self/fd/x to be a symbolic link TO ANOTHER symlink??
