Hi,
I've written a patch to GDB's Python support to allow SIGINT to interrupt a running script to address the bug http://sourceware.org/bugzilla/show_bug.cgi?id=13265 (I've attached my patch to that page).
It works by installing a Python-specific SIGINT handler just before executing a Python script, and restoring the original SIGINT handler after execution as well as at calls to gdb.execute(...).
There's one caveat: if an inferior is running via, e.g., gdb.execute("run"), SIGINT will interrupt the inferior but not the enclosing "python" command. I think it would be better to also interrupt the "python" command, but I'm not sure how to detect this case yet.
