  Still no go -- we can calculate the number of recursions for a
particular call frame size (or expected mix of frame sizes, which is
really the same), but we can't predict recursive behavior inside a C
extension, which is a significant part of the problem (witness the SRE
experience).  That's why PyOS_StackCheck() actually has to do more
than test a counter -- if the counter is low but the call frames are
larger than our estimate, it won't help.
