Research direction

The issue names recursive subprocess.popen calls and KeyboardInterrupt as the failing entry points, but provides no source file, reproducer, or test. Start by reproducing the fatal error around that interaction, then trace the interpreter and subprocess handling involved. Done means the recursive interruption no longer causes a Fatal Python error and a regression test covers it.
