I'm going to change the interrupt handling to not preserve the quit_flag
in cases where the inferior is not running. The download will abort and
gdb will continue as if no debuginfo/source was found. If the inferior is
running and ^C happens during a download, quit_flag will be preserved
and the inferior should see ^C. If ^C happens a second time during the
download then it will abort. This will be accompanied by some help
text so the user knows what's going on. This is my understanding of
what was discussed on IRC.
