On what grounds do you claim that? The timing of arrival of the SIGINT
is basically chance --- it might happen while we're inside backend/regex,
or not. I mean, sure you could claim that a bad regex might run a long
time and thereby be more likely to cause the user to issue a query
cancel, but that's a stretched line of reasoning.
