I was not able to reproduce your problem using your (I believe to be
slightly incorrect) test case:

  bash -c 'while true; do /bin/true; done'

It was always interrupted with a single control-C on my amd64 Debian
Squeeze machine.  I expect this means that by chance it was always
bash running in the foreground process and /bin/true never happened to
be there at the right time.

Since the exit status of /bin/true is ignored then I think that test
case is flawed.  I think at the least needs to check the exit status
of the /bin/true process.

  bash -c 'while true; do /bin/true || exit 1; done'
