I did consider that, but frankly this whole business of "adjusting the
stack" by messing around inside the undocumented jmp_buf scares the
*bleep* out of me. WAY too easy to get wrong, and my asm skills are too
rusty -- and too non-x86 -- to be trusted.

I'm sure it's possible, but IMO migrating libassuan/gnupg is easier --
for me. As it turns out, in libassuan there's only one file that needs
to be modified. gnupg is a bit trickier, but not terrible -- and the
APIs, while annoyingly different, aren't totally dissimilar.
