I'm afraid this belief is urban legend. Credit for pic is due 100% to
Kernighan, not to the contemporary pace of computing practice.

Even in the 1950s, we had one-hour turnaround at Bell Labs. And the
leap from batch processing had happened well before pic. Turnaround on
modest Unix source files and tests has changed little in the past
fifty years.
