I must have done. On the other hand, the C stack (for all programs, not just sh) had a fixed size determined at ld time, because I decided to have the stack grow downwards as it did on the pdp11, even though the interdata could only extend memory segments upwards. I was worried that all sorts of things might break if the stack went the other way, but in hindsight this was probably the biggest mistake I made in that project.
