So far, e.g. git-update-index --refresh was basically uninterruptable by ctrl-c, since it hooked the SIGINT handler, but that handler would only unlink the lockfile but not actually quit. This makes it propagate the signal to the default handler. Note that I expected it to work without resetting the signal handler to SIG_DFL, but without that it ended in an infinite loop of tgkill()s - is my glibc violating SUS or what?
