Ok, here a some more details. All test are made on linux 2.4. I first
tried 2.20pre2, compiled with -DIAMSUID. Aparently, pre2 doesn't work at
all, suid or not. Are there any known problems with pre2 on linux? The
calling process blocks on writing to the speedy_frontend.

I then tried 2.20pre1 which does work. Setuid works too. I then came to
the problem i suspected in my first posting: The following code does not
work, the while(<SOUT>) loop is never reached, but neither the open() nor
the close() fail.

>>>
sub grab_envelope_hdrs {
  select(STDOUT); $|=3D1;
  open(SOUT,"<&STDOUT")||&tempfail("cannot dup fd 0 - $!");
  while (<SOUT>) {
    [...]
  }
  close(SOUT)||&tempfail("cannot close fd 1 - $!");
