The offending function is hypot(2). If I replace it with sqrt(p*p+q*q),
no more stack overflows no matter what are shapes and how complex the graph
is.

I think it is a compiler bug. But need more time or someone's help.

The 'vision' for ape was unrelated to plan 9.

Andrew Hume and I wanted a way to use the same
source for our 1127-developed programs on the
diverse set of machines we had in the late 80's -
Research Unix (v10), Suns, SGI's, and Plan 9.
Before the days of very good ANSI/POSIX compliance.

Yes, we could remove ape from plan 9 now,
if someone cares to port the remaining ape-using
programs to pure plan 9 - I'd be happy to see that.
