Below is a proposed patch to do this.  When and if this gets deployed,
the third arg to %calibrate-stack-depth would be removed, so that it
doesn't generate any output.  But for now it's interesting to see what
results people on various OSs get.

Could people who've being getting "Stack overflow" errors try this
out, and also report (for interest) the ";; Stack calibration" line
that they get?

Thanks,
