Jann Horn noticed that KSTK_ESP + eager task stack freeing was a bad

crash, but I think that using KSTK_ESP on a remote task is
questionable in general.  Therefore, I propose to get rid of the
major users for 4.9.

Ping!

We need to decide fairly soon whether to apply these (or perhaps just
patch 1 or just patches 2 and 3) for 4.9.  For any parts that aren't
applied, I'll send quick fixups to pin the stack in the offending
code.
